I was on the Yoks, year old ones too. They had been sitting in my kitchen, ahh benefits of being single, haha.

It was fun racing with you guys, uh, wait, no not so fun while racing way to much stress. But it was a blast before and after!!

That's interesting, mine are sitting in my kitchen too. I love my Dunlops.

Ah, I knew it was one of you!

Sorry I missed out on the wednesday night driver's meeting but you guys don't know what you're missing when you do your dyno pulls with the baby seat in the back

Thanks for posting your video Geoff, I now know what I was missing on the east course......

Great walking up on awards stage with you guys, except Geoff was on the "high" stage.

thanks for the heads up though!
Here's a mostly stock IX GSR SE for sale:

I still think you should buy mine, though. Especially if you're going to track it. The gearing in the 6spd is better then the 5spd for road racing. I'd do more research on the longevity. I know a local guy with an MR that has quite a few open track days on his.

Has anybody thought about or is currently using a lightweight crank pulley? (Either perrin, gruppe-s, or AP) I've been looking into this trying as of late and was wondering if it was worth it.

It will give you some slightly faster acceleration but not not much overall power gains. Maybe I am just paranoid, but after reading more about internal engine harmonics I would be aprehensive about installing any type of crank pulley besides a Fluidampr. Some engine builders specifically advise against it.

Guys I dont remember talking about wheel spacers. I was looking at Jamie from Works setup and he runs a fairly decent sized spacer (and inch maybe) with its own stud kit.

Of course this will change the track of the car pretty substantially, it will also increase the unsprung weight, and maybe change the alignment of the car.

So whats the consesus? My ssr c's are 40mm and come with a 6mm spacer to clear the calipers as is....

Consensus on what? You currently have a 34mm effective offset. How much lower offset are you interested in running?
I have to use a 20mm spacer (with it's own studs, that bolts on to the stock studs) on my +38 17x9.5" RPF1s. I'd rather not, but those wheels require it in order to clear the front calipers. doing this in front results in reverse stagger and is supposed to improve turn-in (RWD cars have stagger to negate excessive oversteer). If this is what you asking about, there is no consensus. Some people like it and some don't. I don't like not having a hub-centric setup that places the wheels on the studs only and not the hub, but I still use it.
Supposedly very low front offsets and a lot of front track can mess up your front roll center (increases migration?).
I don't know at what point this becomes an issue, but a lot of fast people are using siginificant revrse stagger due to wider front track, both in US AutoX, and Japanese road racing, so I guess you could consider that a "consensus."

Having the same 20mm of spacer on your wheels will results in 20mm effective offset. That's pretty close to my +18. It fills the front fender nicely flush and doesn't rub, even with 255s AFAIK.

Spacers are OK to use, as well as longer studs. The wt. isn't a big factor (we designed very light non- hub centric spacers in 2, 2.5, 6, 9.5 and 19mm thicknesses), and alignment is unchanged. I suggest using APR studs, which will last longer with heavy use. That said, it is more an issue of what effective offset you want to achieve with your wheels. I don't use any spacers.

FWIW, I snapped about 4 KYO-EI 52mm wheel studs from Road Race Engineering within a month or two of each other after two years of use. These definitely had a expiration date/usage limit. I changed wheels at most events for reference.

Are you still using the RPF1s? If so, I assume you're running the +18, at least in front?
