Let's discuss SCCA Stock Class
 

I'd like to get a thread started for those that are going to race their car in Stock Class.

What have you guys done to your cars so far?

Alignment. Tires. Done.

did you get the oem crash bolts to add some camber?

Yeah, didn't want to kill my star specs that quickly :)

For Stock, you're going to need to get some R-comps.

Anyone out there on purple crack yet? If so, how are the tires wearing with the little camber adjustments the car can get? I'm afraid R-comps on the BRZ/FRS will be similar to the HS Minis who cord shoulders after 20 runs :/

There is various information spread across a few different threads in here. The RTR thread is basically stock setup on street tires. There is also another generic autox setup thread.

I have 245/40/17 A6s right now but have yet to race on them the next event is next week and I'm hoping to try them out then. Others have been racing on that size but either aren't on the board or are not as active. I have a 275/40/17 A6 I am going to try and test fit but I doubt it will fit in the front.

As far as setup thus far it's really just an alignment with the crash bolts and some have done muffler deletes and air filters. I have a Nameless muffler delete and aFE filter.

Swaybar options are coming. Right now Cusco has a couple front solid bars, Tanabe has a hollow one, Strano will have a hollow one as well.

Shocks will come too but nothing out right now. The car feels pretty good on the stock shocks.


As for tire wear most have gotten -1.2 to -1.6 in front with the bolts. It won't be like the mini at all. That car has more weight in the front and it's FWD. I would expect at least 70 runs out of a set of Hoosiers unless you are overdriving them.

good info. do you think the r compounds will overburden the stock suspension? is this when you would add a stiffer sway bar to reduce the roll due to the added grip?

we have a c stock street tire index that allows us to race in c stock but on street tires. i'll most likely get a set of star specs once i wear out the OEM tires. do you think a set of 215/45/17 star specs will be too sticky for the oem suspension to handle? would a 'medium' stiffness sway bar be needed to compensate?

I want to drive it with the stock swaybar first to see what the effects are before jumping on the swaybar bandwagon.

You aren't going to really overburden the stock suspension, plenty of guys are using star specs in wider sizes with the stock suspension.

I think a front bar may end up being good for race tires for maintaining camber but also keeping the inside rear on the ground so the Torsen LSD works. Although I haven't really heard any stories of major wheelspin autocrossing. I don't think the car will need a big bar even on race tires.

I think it's going to need an FSB, and might be like the RX8 where it needs one on street tires more so than race tires thanks to the way the Torsen wants to work. The runs I took this past weekend I suffered from the lack of confidence in the rear in transitions so the FSB will be huge until we get shock options that really can fix that behavior IMO. I'll be doing more testing soon, next time on Star Specs after Nationals.

I've driven about 80 runs in my car so far on the Star Specs, maybe half with the stock bar and half with the Cusco bar. It needs a bar. The rear tires just don't connect very well without it. It really needs an even bigger bar, but none is available until Strano releases his.

Maybe this won't be as big an issue once we get some shock options, but for now ...

Des, what kind of rear toe setting are you running with the Cusco?

20mm Cusco?

Phil

One eighth total, dialed back to zero, and now back to one eighth. Until I unlearn my FWD habits, mild push is preferrable.

yes, 20mm Cusco

where did you guys purchase the camber bolts? the toyota/scion dealers are asking for $10 per bolt. online parts stores are looking for $5 per bolt plus $10 in shipping. it ends up being about the same.
