Snow/Ice Rallycross in the Rabbit

My 07 Rabbit at BAC Rallycross #2 2018-2019 (I was having A LOT more fun than I look...) - Kevin Doubleday ©

FWD cars don't win the WRC anymore and they haven't in decades. In fact, all two wheel drive (2WD) cars have been rendered entirely obsolete on the world stage by the original legendary Audi Quattro. That's because 4 driven wheels are obviously far better at putting power down than just 2 and when you are on a loose surface such as mud, gravel, or snow, traction is in SERIOUS short supply. Thankfully, I'm not on the world rally stage or competing for the world title, so I'm happy with my little FWD rallycross car (for now anyway...).

I have already been to one event this season (which is my first rallycross season) in this car. You can read more about it here where I nearly caught air going over one of the bumps. Last time was on gravel, though. This time, it was a snow covered course and what I didn't know was that snow wasn't covering gravel. It was covering ice. What could possibly go wrong?

In what I seriously fear will turn into a tradition, I once again set the slowest time of the day in my first session: 96.47 seconds. If you haven't read my post (linked above) about my first rallycross event, the same thing happened at the last event where I set the slowest time of the day in my first session out. One big issue was my confidence. Feeling like I had got a handle on things after my first event, I pushed harder than I should have and the ice hiding underneath the snow in most corners rewarded me with an almost complete 180 degree spin.

FWD Cars Can Dance Too


My lack of experience doing hot laps on ice was made worse by my decision to fix the balance of the car. Having suffered all that understeer my first time out, I employed the quickest and cheapest guaranteed cure to understeer on snow and ice; leave all seasons tires in the back and put winter tires on the front. The car became more tail happy than a puppy dog discovering toys and treats for the first time. That's exactly what I wanted, but I had forgotten to adjust my driving into the corners to make up for the newfound handling balance. That led to the spin, which cost me several seconds. Fortunately, the rest of the day was much better.

My next session out, my time dropped to 83.63; a huge improvement of almost 13 seconds. I still wasn't competitive, though. My class (i.e. stock 2WD) leader had a best time of 79.41 s the first session out, which had dropped to 76.12 in the second session. As a result, I decided to go out with Dave H. He's a seasoned FWD rallycross driver and was around since the beginning of local rallycross. He pointed out a few problems.

(Rallycross) School is in Session


4WD/AWD cars are clearly a more popular choice for rallycross...

First, I was too cautious with my driving. I wasn't cutting close enough to the cones because I was too afraid to hit one and get a penalty. As with everything in motorsports, if you never find the limit, you never know exactly how close you are to it. He said it took him a few runs (and a few cones) to get a feel for exactly where the edge of the car is. I needed to do the same. I also shouldn't be afraid to hit the cones. If I focus on avoiding them, I will leave too much time on the table.

The second problem was that I was not committing enough to the throttle coming out of turns (sideways) to keep the front wheels pulling me in the direction I want to go. Sometimes, I would back off slightly out of habit to regain traction. That was slowing me down.

Finally, I was too busy with the handbrake. I was using the handbrake to adjust my line mid-corner and I should only use it in corner entry to provoke the back end of the car to rotate, but once I am in the middle of the corner, I shouldn't need to use it anymore (the real problem there, of course, was that I wasn't setting up my line in corner entry well enough to avoid the need for mid corner corrections in order stay on the proper line through the corner).

Not Quite Winning, but...

Yoda's guidance worked. My third session, my best time dropped to 77.10 seconds. Class leader? That dropped to 74.28 seconds; a gap of 2.82 seconds. Nearly 3 seconds is an eternity on a 70+ second lap. But what's important is progress. Last event, my best of the day was a whopping 6+ seconds off the class leader's best of the day and it was nearly 2 seconds slower than the class leader's WORST of the day. This event, the gap between my best and class leader's best was less than half the gap from the first event and it was also over 2 seconds quicker than his worst of the day.

Given that this course is nearly a third (32%) longer, a 2-3 second gap here is also closer than a 2-3 second gap at the last event. It's still an eternity, but some eternities are shorter than others, just like mathematicians will tell you that some infinities are smaller than others. The progress also confirms what I was told at the last event, which is that all season tires were probably slowing me down by 3-4 seconds. My best of the day at last event after I had got the hang of it was over 6 seconds slower than it needed to be, but here it dropped to being under 3 seconds slower, and on a longer course.

My last session of the day, I decided to try starting off in 2nd gear because my front wheels were spinning endlessly on ice during every launch. That can work on the street when you are having trouble taking off in low traction conditions. In competition? The car bogged down, with a session time of 78.09, nearly a second slower. Another lesson learned, don't start in 2nd gear.

Race Car Driver Excuses

I did a repeat performance of my first event; dead last in class. But, if you exclude my first two runs (and everyone else's) where I was learning the course and rallycross on ice, I would have finished exactly middle of the class. Everyone was also learning the course, but at a far less steep learning curve due to my relative lack of experience. Middle of class wouldn't have been great, but it wouldn't have been bad for my second time out. Now I just need to not screw up so badly the first half of the day.

Nearly worn Federal Himalaya WS2 Winter Tires

I also tried to put some blame on my used Federal winter tires. When I went out with Yoda to help me, I noticed his car (also FWD) had far better traction. I told myself I must just be making excuses. However, we were hit with a decent snow fall a few days after the event and I was driving the rallycross car on the road. Having a much better frame of reference on the road, I noticed that the grip from my tires were in fact much worse compared to every other winter tire I've used on the road.

Time for new, better winter tires perhaps? I'm certainly tempted. I think I will put the crappy winter tires on the back and put fresh winters on the front. Stick around to find out how the next event goes, which is this coming weekend!

And this is why you want an AWD car for rallying...

GTR vs Evo X vs STI: which has the best AWD system?

A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track load

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one. The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would

Michelin PSS vs Firestone Indy 500 - Track Review

A couple of weeks ago, I posted my first impressions of Michelin's PSS vs Firestone Firehawk Indy 500 tires. I've run PSS's for several years on the Boss, but I'm trying the Indy 500's for the first time. In short, I was worried about the narrower tires (I was running 285/35/18 PSS but could only find the Indy 500 in 275/35/18) and tread squirm, but I was happy with them up to that point just driving on the street. I had the chance to drive on them for three track days now. So what were they like? After my first session, they made an impression that basically persisted for the rest of track sessions on them. Phenomenal, unmatched value. Now, if value is something that stands out above all else, it typically means the compromise between qualities you want and those you don't is less than ideal, but the value is attractive. This is no different. I'll start with the bad, which really boil down to two: ultimate grip and grip longevity. Grip is noticeably l
