Depends on your site. Someone who runs at Devens or Meadowlands can see like twice the usable tire life than someone who runs at Lincoln.

Somewhere between 35 and 150 runs If it's on a rough site and a camber challenged car it's not long. On a car with a good camber curve, good balance, and a smooth site you can get 40ish competitive runs from a set, then after that you're giving up performance. I've taken tires to 130ish runs on my car but was....a ways off the pace. Slap a new set on for a big event and people that were beating me by 2+ seconds were then the same amount back from me or more.

IMO 40 runs (with a co driver) is about the end of the national quality runs on anything with camber. I normally just take tires to the cords, because I've been in a spot where I can easily beat the local SSM competition on 160 run slicks but even on stickers I cant take the national level competition (the car can though). You guys with tin tops do have a nice advantage. You can buy the super cheap american racer non-dot slicks and run them in XP for non-important events. Supposedly they like the same setups as A6s and are just as fast but for the circle track guys they are fast for 20 saturday nights, and only cost like $130/tire for 275/35R15s.

20-40 runs does seem to be the accepted "no longer competitive" range depending on the car depending on how deep your pockets are and car setup.

I'm on a 2 set year this year, but hoping to do a single set next year and find some takeoff 315's in case I need a "tide me over" set. The 315's seem to last longer (surprise) and handle the heat better (also surprise) so I might find they're happier, longer. I've got 13 runs on the set that'll be on the car at Wilmington, but after the 12 runs there they become a local set. Until now the car has been on takeoffs all year (except Dixie and ATL Tours)

You're really struggling to get 315 take offs? PJ has an entire basement of them that he doesnt know what to do with. Like literally its like 30 sets of tires.

Ok sounds about right for mine then. I got about 38 runs on my 285's with mostly concrete runs then a few locally on normal asphalt. Just pulled them off after this weekends events and one showed some cord so thought I would see what others were seeing. Thanks!

The last time PJ and I talked was....2009 I think? I didn't decide to go to 315's till this past winter and when I put the "WTB" out then on the sandbox I only got replies from Martin. Maybe I shouldn't be such a dick on there

I'm sure I'll chat with him this year and actually meet people now that I can say "this is my car" vs "I'm building an SM car". I always laugh at the difference between those two comments. "I'm building an SM car" = noob with a not running hunk of junk in the garage. "This is my car" = Ok, we can talk and actually be friends on facebook

"I'm building an SM car." Were you the one scoping out my wing last year in SSM grid for the west course?

Probably. I introduced myself, but you were rather busy at the time. I was there to watch Chuck Pyanowski as he's from my home region but recognized the green wing on yours. I gave up telling people about the Whitebaru and just started saying "I'm driving a VW in FSP" as that made eyes glaze over less

What wheels are you guys using for the 315s?

I would start off with the 275/35/17 on a 17x9 rim on the BRZ just because I already have the rims and they will easily fit without modifying anything. I also would see if I could get the car under the 2480 minimum weight. However, I was curious what width people went to for the 315s? I know lots of Corvette guys just run them on 10" rims with good success in road racing and autocross, but a 11/12 would be better. Forgestar is selling their 18x11/18x12s F14s now for like $350/wheel which seems pretty cheap. 17" they top out at 17x10.

If you were going to get that staggard setup I'd but the 12's in the front and the 11s in the back. The front tires gain a lot more from being on proper width wheels than the rears.

315's like 11's.

Forgestar doesn't have the right offset for the GC/GD/GR chassis, but might have one that works for the twins (not that you couldn't fix it with spacers for the earlier chassis).

While you have 9's I don't think you'll stick with them for long if you want to be competitive anywhere other than locally.

I just meant 11/12 as in available widths, I wouldn't run a staggered setup.

Forgestar will do the F14 in 18x11.0 from +23 to +55 and 18x12.0 from +36 to +68.

Lots of people run an 18x9.5 square setup with a +35 or +38 offset with 275 street tires. George from Florida who used to have the GTR ran the 18x9.5 Mach V wheels with 275 A6s without any issue.

The 18x11 +23 F14 with 315s would likely barely work on the inside, but it's going to stick outside the front fender, the 18x9.5s +38s just barely work inside the front fender with about -3 degrees of camber. But alas there are ways to fix that. The 315 is so damn tall is just exacerbates the issues.

All I hear is bitching when I should be hearing the sound of you fitting the tire that'll make you go faster.

I'm well aware of what lots of people run, lots of people are wrong and choose to do the easy route.

Or you can be classy and use a Dewalt angle grinder, but that's big budget racing there

Yeah the angle grinder with cutoff wheels works a whole bunch better. Buy saying sawsall is funnier.

The comment about "alas there are ways to fix that" was definitely talking about making the necessary modifications to make things fit. I have a decent sized compressor and a Snap-On cutoff tool. I still have a GC8 shell in my garage cut front and rear to fit 16x10s (now on Jay's car) and 275s back in 2005. It's too bad Real doesn't make 17" shells.

I'm just thinking out loud really and trying to visualize how much more space I would need for the 315 vs. what people are running right now. One nice thing is there is an overabundance of wide body items for the car that are relatively cheap. Some are just too wide though, guys are running 0 or negative offset rims to fill them out... I'd like to add as little width to the car as possible.

The only bitching is about how tall the 315 is.

Plasma cutter FTW, until you find some panel adhesive and set the car on fire. Everyone sets their car on fire though, right?

Its better when it catch on fire while you're racing and you have to put it out with the tire sprayer after every run.

Luckily, I've only ever caught the lemons car on fire while on course. The Subaru has smoked a lot in the past, but never caught fire. At least on course.

Welding fires suck.
