What is your SM2 Set-up??

[mopwer]

I'm running SM2 in my 93 Turbo and its not very competitive the way its set-up. The CT-27 bumped me out of ASP. Plus, I have never had good tires. Just ordered some 205 Kumho V710s for the front, and I have some used Kumho 225 V710s for the rear on the stock 15" wheels. I'm currious as to how much difference they will make over the used R compound and new Azenis 615s I've been using.

What are some of the SM2 set-ups being used and how competitive is it? Please include everything from tires to alignment to engine. Thanks.

I'll be watching this thread. I am competitive sometimes, not so much most of the time. I have Falken ZIEX 512's on 17 x8 (215's)and 17 x 9.5 or 10(not sure which, 255's). CT27a at 4-5psi. KYB AGX's and Falken springs(new and breaking in both).

race tires will make a very large difference....

[Wangan_X]

on a 60 sec course i would expect 2-3 secs

dance, you are running that beast on all seasons at the autox? wow, i bet its a handful

my car is sm2, but its a mk1, so i don't think my setup will help

[Wheelman_13]

Coilovers? If so, then i haven't a clue what to do with them apart from corner balancing. I run in stock class, so anything I say may or may not apply to you. I go for as much negative camber in the front as I can without causing clearance issues with the struts, and only slightly less in the rear. like -3 front -2 rear or something close to that depending on how well it's held the settings with me driving it daily.

and
+1 for tires
New R-comps = really really sticky. That will probably make more difference than any other minor setup tweak. I'm surprised the car was even drivable with streets on the front and race in the back (if I understood that correctly).

Running the stock 93 springs and AGX struts set to 3f/1r (seems to be the best setting for neutral handling).

I was either running the Falkens or used R compounds, not both together.

Just looking for other set-ups and how well they work.

Weight - around 2700lbs with me in it

I think considering that my car is basically a daily driver, I'm running very conservative wheels/tire sizes as well as alignment, I'm pretty damn competitive when locally I'm always in the hunt for FTD.

If you want to look to someone for a nationally competitive SM2 setup for the MR2, look at Randy Noll out in California. He is already giving the established RX-7's a run for their money and he's just started developing his quick spooling stroker 3sgte.

yeah, just copy his car.... heheh

You should tell us what your suspension and alignments settings are right now. SM2 is pretty damn competitive, but then again, region plays a HUGE role.

This last autox, with me in ASP and running allseasons, all 5 drivers/3 cars (M roadster, Carrera4, and me) were within 1 second of each other. I was surprised that I wasnt 3-4 seconds behind them.

I assume the NSX items are a good bit lighter than the stockers?

Any reason you've not gone with wider tires? I've heard that 225 is workable for the front, and wider still in the rear w/o too many clearance issues. I'm sure it's plenty of grip for 2700lbs loaded at any rate.

Pick up some RPF1's in 17x9.5 and 17x8.5 and wrap them up in some Kuhmo 710's or hoosiers. You can also go with the RT615, I do and they rock. My setup was: stance is as wide as possible and try running 100% negative camber up front, locking down the rear and setting the fronts to about 1/4 off of the stiffest setting. Sped me up quite a bit from the other settings that I had played with.

It is very difficult to be competitive in auto-x with a turbo in anything except B Stock. ASP and SM2 are very fast. Hoosier makes a 275/35/15 in an A6. Put those on a 15x9 or 15x10 for the rear, and run the 225/45/15 A6 in the front on a 15x8 or 15x9. That is a wheel and tire setup that can be competitive in ASP and SM2. Then you need a good coilover setup. The KW Variant 3 setup looks like it would be good, with an Addco or ST sway bar up front. Also, you need a good auto-x alignment, with a lot of negative camber, max caster if it is a 91-2, some toe out up front, and very little toe in the rear.

I ran B Stock the last 5 years, but am running the 88 SC this year in CSP. I would like to convert my 93 to a track setup, so I am looking into that wheel and tire setup, except using the R6 instead of the A6.

leave street tires for the kids in the street tire classes

KW is the best off the shelf I've seen... wish we had more good options

I don't own stock '93 wheels but I'm sure the NSX wheels are pretty close in weight considering the difference in size/width.

If I get a new set of v710's for my NSX rims I will probably try 225's instead of 205's(although I do see some rubbing on the spring and putting in more camber may make that worse combined with a more bulging tire). Last time I ordered them, I didn't feel like dealing with the headache of possibly running into fitment issues. As for the rear, the only bigger option for v710's on 16's is 265/45 which I wouldn't put on an 8 inch rim. Kumho was supposed to come out with a 245/45/16 this year but I haven't heard anything about it and was sorting of waiting on that.

I've done my best, but it's time to change. Looking into new rims and tires now...

Cool, thanks!

I don't want to get too crazy with my street car. I'm trying to make room to build a Mk 1.5 track car with a Gen 3.

Right now, I have 205/50R15-F and 225/50R15-R Kumho V710s (fronts are new, bought the rears used) on stock wheels. Never ran this tire combo yet, but will run my first ProSolo this Sunday! Running camber plates on the front that give me about -2*min. and the rear is set at -1.8-9*. Stock 93 springs and sway bars, KYB AGX struts set to 3F/1R, going to 4/1 didn't seem to help oversteer any on the street tires, new tires may be a different story. Car has the power steering. May look into the QR rack pinion. Car weighs about 2895 with me in it (what a pig! - me and the car;-) ).

I forgot about toe in. Rear is just slightly toed in and the fronts are toed out quite a bit with the camber plates pushed in.
