What does everyone like for clutches? I've got a South Bend that seems to let go above a certain torque (odd since the oem clutch before it held fine).

I'm thinking about just getting an Exedy Hyper Twin and being done with it.

Are puck clutches okay to live with? Is an organic type more likely to survive if you slip the clutch just a little too long (over a carbon or ceramic?)

Edit: I should add 6MT with 1.5way R160 and all WRX axles

I'm running a full face Competition Clutch in my sm car and has held up to 400whp for a few seasons now, pretty happy with it.

I also use a full face organic clutch, but from Exedy in my SM car. Has held up to 475 wtq for a while. I like the idea of a twin disk, but the full face setup is WAY cheaper and keeps working.

I also run an Exedy. I tried the 6 puck at first and hated that decision. The motor had to come back out for something not-clutch related and I swapped to a full disc and I love it. I'm at like 360 tqe

I'm running the ACT sprung 6-puck disk with the HD pressure plate. It's holding up well at 525wtq. I have launched on it well over 100 times in the last 2 years, it has not yet slipped at all. The engine came out for a spun rod bearing and it had plenty of meat left on the disk. It is a little chatty in stop and go traffic, but since the car see very little street time, I have no problem with it.

I see people running 255/265 tires for WRX 15+ auto x runs.

Has anything changed? From my understanding, the max width for WRX allowed is 245 correct?

What class? This is the Street Mod thread and SM has no tire limitations.

^ Street touring tire allowances (STU) did go up to 265 within the past few years

ACT Full face organic here as well, i've seen too many twin and triple disk cars have all sorts of driveline breakages

What do you guys think about running RE-71Rs in SM? I know I can run stickier tires, but I have some 255 width RE-71Rs left over from a street class car. Am I going to be seriously slower this season than my Hoosier running counterparts?

You will be giving up a ton of potential time by not running A7s

I would say yes. Because 255 is not close to being wide enough for SM regardless. I use to run 255 re71 in SM and the other people were running 295+ A7.

So if you're considering 255's just accept it for what it is and know that you won't be putting down stellar times. You may be competitive locally in SM depending on what you have for local drivers.

As stated, depending on who you have locally, 255 street tires may be enough for fun. Anyone with a remotely prepped SM car on hoosiers will do some damage though, and national level cars start at 315 A7's.

I need to get on the 315 band wagon. Just not prepared to make the jump/work needed to go up from my 295....

that depends on how you define "seriously" ...but yeah, YES.

that said I won the Packwood tour in ASP, on RE71Rs, just depends on who shows up and on what tire.

Its rare for people to run Hoosiers in SM in small local events. Usually SM are the folks with a bunch of mods that aren't too serious.

Our first regional event there were 5 Subarus running RE71Rs in SM, it was fun

Yeah, that's what I thought which is too bad. I think eventually I'll try to modify the car back down to STU to shield myself from the burden of buying A7s.

Right now the car has a bigger turbo than stock and is catless. I don't think it's responsive enough like that for autox anyways and would probably be faster in the tight sections with the stock turbo. The previous owner had it built this way. Maybe when I'm ready I could find someone who would want to trade turbos.

Edit: I should also mention that the car has an IAG stage 2 short block. I'm unsure if that would also keep me out of STU if the compression ratio was not changed, and if the part is not add performance and only adds durability. If that's the case, I probably will not be going to STU ever.

I run in a couple local clubs (CMC in Maine, and SCCNH in NH) as well as NER SCCA. There's a small but serious crowd that runs Hoosiers in prepared in SM classes. That said, there's also a lot of "accidental" SM cars. People who are more into the car than the sport and have found themselves classed into SM rather than trying to arrive there. I bet I'll be able to have some friendly competition with them despite my RE-71Rs.

NER is the home of G-Fab. Lots of good SM people there in all of the classes.

A built, non OEM motor, regardless of it actually makes the car faster puts you in SM anyway

Nobody does. FWIW, I went through 3-4 OEM motors during my years in STU

SM in our regions around here in the midwest(Wisconsin/Illinois/Iowa) are all pretty competitive and at least 2-4 cars show up with 295+ Hoosier A7's per event.

I just build a new A2W intercooler setup and it works pretty good, but water can climb up a bit too much after a few runs. I was at Seneca and I have seen 2 people (1 in SSM) puting ice in there reservoir and telling me it's legal. I check the rules, can't find if that's legit or not. Any opinion?
