SCCA C-Stock 2013, RX-8 competitive again?
 

http://scca.cdn.racersites.com/prod/...-july-solo.pdf

fyi, FT-86 is now in SCCA C-Stock.
more importantly, SCCA likely will move MS-R and Z0K to BS.
I'm guessing the RX-8 will be a lot more competitive in CS again.
Makes me miss my RX-8.

If the MS-R/Z0K move goes through (and I'm betting it will), then yes, the RX-8 should be competitive. The RX-8, 370, and BRZ/FRS are all pretty evenly matched, IMO. I think the "regular" NC is still overmatched. Each has its own strengths and weaknesses, but I think the best overall package is the RX-8.

Should be an interesting class.

^Agreed

and as I said in the DSP thread, please write your letters in support of the move.

Thanks for the link Chris.

Letter sent.

maybe competitive, it just depends if the how competitive it is against the new car and you're also overlooking how competitive the standard Miata has been over the years

Way to go out on a limb there, Mark. Might be competitive; depends on how fast the other cars in class are. ;)

"Yankees might win tonight; it depends on whether they score more runs than their opponents."

Are you talking about the NB Miata? B/c I haven't seen anyone having much success with a "regular" (i.e., non-MSR) NC.

Maybe Mark is alluding to putting a rear bar on a non MSR NC?

Or the fact that Buetzer in a '99 Miata used to beat Isley half the time at local events?

I don't think the MS-R rear bar will work without the MS-R front bar to go with it, but a bigger rear bar may help th NC Miata..

Don't overlook the 370Z either. Since we have yet to see the potential of the FT-86 it would be going out on a limb to claim anything for or against. I'm not all that impressed by it, but I could also be wrong.

I'm not that impressed with the FR-S yet either. Maybe if we find out that they can get 2.5-3 degrees of camber with the crash bolts, but based on secondhand info, the one at El Toro that had crash bolts was at about 1 degree.

I thought we were offering our predictions, which by definition could end up being right or wrong. ;)

I think the RX-8, 370, and twins are all going to be pretty close to one another.

Feel free to express it in your own view, as will I.

I got to drive against a CS FR-S this weekend... stock but with r-comp + alignment. Here are the results (I'm 16th, FRS 14 and 15):

Keep in mind that I've got a heavy Shinka and I'm not the most competitive driver.

I also got to drive the FR-S for fun runs, here is how I would compare the two, out of the box and on all seasons:

FRS Goods
-More front end grip... great turn in
-Smoother weight transfer, specially under braking
-Good low end torque and revs up pretty high
-More headroom for helmet
-Brakes

FRS bads
-Exit speed... the rear doesn't grip
-Feels like a toyota
-Interior / user interface is less intuitive... long clutch throw... big steering wheel... lots of wasted space
-Power band is really weird... hard to get it to redline

Overall didn't feel as fast for a faster course... it might have the advantage on slower / tighter courses.

2021 here... interested if anyone out there is still running an RX-8 in CS against the cheater NDs. I'd like a comfortable, low cost daily that can also do C-street. not expecting to be competitive... but to have some fun. I've got a DSP RX8 for hillclimbs and may de-tune for SCCA TT Tuner 4.

"cheater ND" owner here.

CS RX-8 will be more than competitive against ND2s at anything but the best national competition (or if you have a particularly quick local region)

Could the new Yokohama A052 in wacky 225/35/18 be a short, hot setup?

there’s a new pair of Twins coming to town :suspect:

Probably worth a try. Kenton ran 245 BFGs on his RX-8 the past couple of years

Doubt they're going to shake up CS, but will gladly be proven wrong. I loved my STX BRZ

225 seems a bit skinny for street tires (on an RX8), but I haven’t really been following the street tire trends so much

a 20% displacement increase at the same weight, seems like the twins might be back at or better than when they were on E85 and thumping on the RX8 pretty good in those earlier years :dunno:
.

The 225 Yokohama is pretty wide, even vs the 225 RE-71Rs I ran on my CS ND. Granted, you're depending a lot on making up a grip deficiency vs 245s with the shorter height and subsequent thrust increase albeit lower top speed.

if an RX8 weighed 500+ lbs less my mental-exercise opinion might be different :)

Exactly :)

I’m a new RX8 owner and new to this forum. I can’t start a new thread so I found this one as most appropriate. Need some tire advice. It’s a 2010 RX8 with the only known mod being a mid pipe. I ran one SCCA solo in CS to get acclimated to SCCA. Ran on the dry rotted 225/35R19 that the car came with. I’m ready to buy new tires and plan to go with new rims also (current ones have met many curbs). The car is only used on race day and not currently trailered. As a driver with no racing experience I’m told the Bridgestone RE71R or Toyo R888 are good choices for DOT compliant. I guess my question starts with...is CS a good place to be? If so, what size tires can I use and do you recommend? I like the idea of staying close to stock to not throw off geometry. Thanks in advance for any input.

The RE71R is out of production. You can find some remaining stock lying around, but it hasn't been produced since last year. The R888 is NOT an autocross tire. It's a general duty track tire and will not warm up quickly enough to be effective for autocross. Plus, with its 100 treadwear rating, it kicks you out of all of the Street classes that require 200+ TW tires.

The current crop of competitive 200 TW street tires are:

- Yokohama ADVAN A052
- BFGoodrich G-Force Rival 1.5 S
- Dunlop Direzza ZIII
- Falken Azenis RT660

The RT660 is new this year, but all signs point to it being faster than its predecessor. All of them are reasonably competitive, there's not one that seems head-and-shoulders above the rest, unless the RT660 ends up surprising everyone.

sooo... before the others jump on this, i'll offer a bit more than tire advice. one is to read the rules. i'll throw out that a midpipe is not CS legal, nor is the toyo r888 as it's 100 treadwear (100TW). For CS, you'll need 200TW tires or higher. The RE71R was/is a good choice until they're sold out. CS is a great place to start, because you can learn to drive the car and have fun without worry about doing a ton of mods. further up the food chain is STX and DSP and beyond. docwalt is doing well in STX. I'm also running my daily driver in STX, although i am significantly underprepped (but still doing well).

i don't know what your tire choices look like for 19" wheels,. but i think that 18" or even 17" wheels might be the way to go. lighter, cheaper, more tire selection, probably better gearing.

welcome to the club!
