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.

3. Elongated studs: your best bet is to get the FPP hubs with elongated studs instead of reusing the old one. Bearings are consumables anyway so if you're like me and you've been enjoying your car for several years, it might be a good time anyway. They are a bargain considering that they come with ARP elongated studs already pressed in. https://lmr.com/item/M1104A/Ford-Racing-Mustang-Front-Hub-Pair-With-3-Arp-Studs You will need open ended lug nuts which are sold separately.

4. A good quality 11" wheel: APEX of course! I got square APEX EC-7 19x11 ET52 for rotation, although they do sell a different offset 19x11 so you don't need a spacer but the spacers will likely pay for themselves quickly in tire life (allowing rotation).

I can guarantee you, once you've put a decent 305 wide tire up front, you'll never go back to anything narrower. The car is a different animal. And it IS an animal. I put Bridgestone RE-71R's on. You can read my review here, including how they compare to my previous setup.

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 loads.…

Post-refresh 2015 F30 3-series pictured. 
Which is better, an F30 3-series or an E46? The F30 has certainly taken its fair share of heat. But if you thought I was going to say the E46, you'd be dead wrong. The F30 3-series is better. Far better. It is quicker, faster, safer, more practical, more efficient, more refined, quieter.. the list goes on. A lot of reviews and people I talk to consider the F30 to be an abomination. Frankly, I don't see it. You'd have to be mad to think the E46 is better. Completely out to lunch. I don't know who in their right mind would prefer the E46..  Trouble is, since when were people buying sports cars in their right minds? Here, lies the real problem.
