3 Replies and 3682 Views Largest legal rear spoiler in SM  3682  3 Started by  toy4speed Hi All, I've been running a my old DSP legal rear spoiler on my now SM Supra for several years, and been trying to determine how large I can build the rear spoiler.  DSP has 10' in height, from bodywork limits, and I was thinking of making it higher, but there is no discussion of spoilers in the SM rules.  I will eventually go to a wing, but for now, wanted to tinker with spoiler design till time and finances allow a wing design.  Rear wings in SM allow 8 sq feet in area, tha...

11 Replies and 4533 Views New Hankook RS-3 in 195/50-15 in STC/STS  4533  11 Started by  BrentGlad I'm curious if anyone has done any testing of the new Hankook compared to the R1R in the new 195/50  I ran the 225 a couple years ago on 8's when I ran the Civic in STX and wasnt too keen on them as I was a single driver and it was impossible to get heat in them, but with the new 'softer' compound, and smaller size I think they may be a viable replacement for next year with the 200TW coming if Toyo doesnt re class the R1R.  Thoughts

3 Replies and 3534 Views STS legal Miata engine management  3534  3 Started by  FSMMX5 I'm having trouble navigating all the STS and MegaSquirt websites and forum threads on this. I looks  like things are easier than a couple years ago with the emissions stuff. It seems like the people that were building these have moved on to other projects.  I have a 1990 Miata I am building for STS. What's needed to stay withing the rules now Just a Megasquirt in the ECU case  The way I understand it, you can only use OEM sensors that came on the car, and you are ...

8 Replies and 2464 Views Another wut class thread  2464  8 Started by  coneassasin Hate to clutter with another classification thread, but I'm pretty confused at this point. Locally, I have a very nice class I can run in which only restricts that the car only run a 140 TW tire. The problem happens when I start going to other regions or competing nationally. If there is something I can change or remove that could square me in a nice national street tire class, I'm all ears. Car is as follows. 1991 Camaro RS 355 CI L98, modified aftermarket intake, headers, tune. This knocks m...

8 Replies and 2711 Views What defines a fender?  2711  8 Started by  the3lracer A member of my region is asking questions about modification of his 1990 Miata for SSM. One of his questions is regarding how much he can legally modify the fenders (specifically the fronts) while still being legal. This has sparked a mild debate between the two of us in regards to what legally defines a fender. 16.1.I of the SM rules governs a majority of the bodywork (including the bodywork in question) for the SM classes, but it only states that it may be 'modified or replaced'. His pseudo-rh...

I have 18'x9' rims and was going to get Direzza ZII in a 255 series but the load rating is to low. so what do you think would be the better option  for fit and performance between the BFG Rival in 275/35 or the Direzza in 265/35 both were measured on 9.5' rims on TireRack,s spec sheet and both list 9' as smallest rim width. Our course is on asphalt.
