I'll find out later this week or next. I don't anticipate any problems and I'm sure others are doing it..?

I've read that others have done it, I think even in this thread. I ordered a set of 245 tires to mount on my stock rims to race the remainder of this season and happened to to check the distance between the tire and strut body and there is no way they will fit. I don't want to give up the camber so I might have to order a set of 215 tires to race with.

Good chance they're not using stock wheels I guess.. I have a set of spacers laying around I may need to use. Remember that a 245 pinched on a 7" wheel isn't going to be as wide as if it were on a more "appropriate" wheel.

Most of us using 245s are using +42 offset rims. With a 5mm spacer they would probably fit. I have 225 BFG Rivals mounted on the stock rims and they just barely fit with the camber bolts, there is no way a 245 would fit.

you will need a 1/4" spacer (5mm will do) on the front wheels if you put 245 tires on the OEM wheels.
but you will only get 3-4 turns of thread engagement with the lug nuts. i live with
this for autocrossing but it is not safe for driving on the street.

You are not allowed to modify anything like taking out the rear seat to reduce vehicle weight.

Right. Specifically, there's no rule that allows it.

I found they aren't AS terrible as I had expected, but not good. Most of my issues have been holding traction under braking... it's really a crap shoot whether they grip, slide, or lock up the wheels and kick on the ABS. I've found they do not hold traction well during steady state cornering and the rebound damping in the rear is what lets the car down when it comes to fast transitions in slaloms. I think the tires have more to give in this regard. The turn in is better than expected but I'm trending to the conservative side of entry speed to prevent mid-corner washout. Putting power down really hasn't been much of an issue, and the lot we use is quite gravely.

Through 2 events this season in my completely showroom car I was back 2.8 (~54 second course) and 1.35 (~49 second course) seconds respectively of last year's detroit region PAX and Pro class champion. He is in a RTR FR-S with a FSB, exhaust, and BFG Rivals. He was 1st on PAX at the opener and 2nd by thousandths on PAX for the second event.

We have not tried swapping cars to really try to figure out the gap between prep and non-prep.

My suggestion for C-Stock depending on your budget is stickier tires- Nitto NT-01, Hankook ventus Rs3, Nitto Nt-05 etc etc, better brake pads, shocks, solid front sway bar, light weight exhaust or you can just take off your exhaust at the event and drop in air filter.

So far I am placed 1st in C-stock with the FR-S and my 3rd event is this June 23rd.

Here was my last event in SOLO: [ame="https://www.youtube.com/watch?v=jbgVYUIC2z4"]SCCA SOLO EVENT 2 2013 FR-S - YouTube[/ame]

My video looks the same, with a GoPro handlebar mount on the tow hook.

I still need a better mount, the shit shakes hard! I have to use tape to add more stabilization to prevent your eyes from rolling in the back of your head lol.

Ran my second event today. Had some more embarrassing DNFs but finished a little less than a second off the guy they tell me is the best driver in the region in a CS Miata. I definitely want to go with the C71 compound Hankooks next time and they are still screaming for front camber.

One section of the course ended up dropping me under 4k in 2nd gear. I never did try downshifting. Does anyone use first gear? It was a pretty short section and I can't imagine I could have saved any time but I'd like to see when people DO downshift.
