The Snake Strikes Back! SRT Viper Time Attack sets Laguna Seca record.




A while ago, Motor Trend held a comparison between a 2013 Chevrolet Corvette ZR1 (with the ZR1 High Performance Package) and a 2013 SRT Viper GTS (full post: 2013 Chevrolet Corvette ZR1 vs 2013 SRT Viper GTS). The soon-to-be out of production Corvette ZR1 didn't only beat the new SRT Viper GTS, but it also took the title of the fastest production car on Laguna Seca - yes, the outgoing ZR1 broke the lap time record for production cars around Laguna Seca. To make matters worse for the SRT team, the last record holder was a Dodge Viper SRT10 ACR. Ralph Gilles, the president and CEO of SRT, wasn't happy to say the least.

Enter the SRT Viper Time Attack - a more hardcore track-ready version of the new SRT Viper (although not as hardcore as an ACR which is still in the works). The Viper TA uses lightweight matte-black Sidewinder II wheels wrapped in sticky R-compound goodness - Pirelli P Zero Corsa tires. They then dial in "significant negative camber" at all 4 corners to take better advantage of the sticky tires. Lightweight SRT Viper seats further reduce weight, with accommodation for 5 and 6 point racing belts.

To make sure the chassis and suspension can confidentially handle the added grip, retuned two mode Bilstein dampers are used with adjustments made to the factory user-selectable Street and Race mode suspension settings to offer firmer damping than the Viper GTS. Firmer springs are used in place of the ones used on the GTS. To make sure it stops as well as it takes off and turns, the existing (and excellent) brembo brakes are updated. New two-piece rotors with increased thermal capacity are used for additional resistance to brake fade.

The usual track-ready treatment from SRT always includes added downforce and the Viper TA is no different. Carbon fibre rear deck lid and two-piece front splitter work together to provide 238 lb. of downforce for a total of 278 lb. at 150 mph.

The result of all of this? The Viper TA took back the title as the fastest production car at Laguna Seca from the Corvette ZR1, posting a lap time of 1:33.6 (full post: 2013 SRT Viper TA First Test: Ralph's Revenge). The SRT team probably wouldn't have had it any other way.

Although that's a great feat, the current C6 Corvette ZR1 is on its way out of production to be replaced by the C7 Corvette Stingray (learn more about the C7 Corvette here: The Stingray is back! Details about the new 2014 C7 Corvette) and GM has already confirmed that the entry level Stingray is quicker than the current C6 Corvette Grand Sport. The C7 ZR1 will no doubt be a lot quicker than the current one. Not only will it be lighter, more aerodynamic and utilizing a more rigid chassis, it also might be packing about 700 hp (full post: 700 hp C7 Corvette Stingray ZR1 may be in the works!).

But that's not a problem for the SRT team because an SRT Viper ACR is also in the works and a C7 Corvette Stingray ZR1 vs SRT Viper ACR battle is bound to happen. Do you think the SRT team will be able to hold the lap time record after the Stingray ZR1 and SRT Viper ACR come out or will Chevy steal the shortly-held title back? Sound off in the comments below!

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

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

Bridgestone Potenza RE-71R Track Review

2012 Boss 302 on square 305/30/19 RE-71R's at AMP - Graham MacNeil © For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are: 1. They grip as well or better than most R comps. 2. They don't wear as quickly as R comps if driven occasionally on the street. 3. They work better in the rain than R comps. The cons were limited to overheating quickly when used on track (being an autocross tire) and wearing too fast on heavy cars like mine. In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman

Stock Suspension S197 Mustang With Square 305/30/19's

If you've had any doubts about whether or not they will fit, fear not! You absolutely can run square 305/30/19's. I had a lot of doubts before pulling the trigger, even more so when the wheels where on the car. The tires do poke out a bit and I figured rubbing is all but guaranteed at full compression but I couldn't be happier I trusted APEX and those on here who have run it. Here's what you need: 1. Camber plates: I have MM C/C plates and they are maxed out at -2.3 deg with the stock struts. I have been running them for years with many track days without issue. 2. 1"/25 mm spacer: I have Motorsport-tech 1" spacers and they look like high quality units. There is maybe a 1/4 inch clearance in the back so you can't go any narrower than 25 mm. http://www.motorsport-tech.com/adaptec/car/ford_s and you want Design 2. Motorsport Tech 1" Mustang Hub-centric Spacers 3. Elongated studs: your best bet is to get the FPP hubs with elongated studs
