Any recommendations on which car to plug in to tire rack's website to get the right 17x9x35-40 offset wheels returned in their crappy "made for idiot's" search engine? I just want to see results and options!!

 

The IS350 and Mustang are a good choice. Or just PM zoom4three.

 

Forgive me, but what are 'stupid JDM tuner lugs,' and how do you know those SA70s need them? I just use a set of tapered lugnuts for my TC005s and they work fine.

 

NM. I just put in a standard model RX8.

 

You have to understand that even though all the wheel specs may look OK, the one issue they don't tell the picture on is brake caliper clearance. There's no spec for this, plus the general people just F'ing up or trying to be experts on something they know nothing about. So TR doesn't want a bunch of wahoos ordering wheels and then turning around to return them because they don't fit

 

Right. That's true and we need that information along with bolt pattern. It would be nice to have an "advanced" wheel selection engine with the required dimensions available to plug in.

 

got mine yesterday, the original 1-pc SSRs are so light, pure love ....

 

Found another possibility

Best 17 x 9 option IMO would be the SSR Type C-RS

 

Just a quick heads-up on another STX wheel option that we have developed. The new TRMotorsports C3 is expected to arrive in mid-March at the Tire Rack.

17x9, et48, 5-114

They were designed as a lower cost alternative to other performance oriented 17x9 wheels on the market and can be pre-ordered for just $159 now. Construction is gravity cast, shot-peened and heat treated for additional strength, very similar to our popular Kosei K1 and K1-TS wheels. While not the lightest 17x9 on the market at approximately 19.5 lbs, it is a reasonable alternative for a tighter budget or a back-up/rain wheel.

oh great, I'm trying to help you sell the best and you post up cheap crap

 

Well Mr. Team - if I didn't spill the beans here first, you would be kicking my butt for holding out on the forum members

Good luck with the build Mark, I am looking forward to seeing what you put together this year.

Have they been fitted to an RX-8 yet or is that one of the target cars they were built for? The spokes in that pic look a bit flat i.e. caliper clearance

 

Mark - "Fitted" in the virtual world would be the honest answer to your question. Comparing our CMM scan of the RX8 brake package and the CAD drawing of this wheel design indicates a minimum of 11mm clearance at the closest caliper interference point. It's good to go.

0.6# lighter for $400/wheel vs rpf1. Don't know if that fits my idea of "best"

 

+1 to that. You can get RPF1s for roughly half the price.

 

I'm going to 17x8 +35 Kosei K1TS I bought used off the Evo forum for 575 shipped.

My problem is obvious that they're not wide enough, but another local was able to wedge 255/40/17 Star specs on his 17x8s. . . so I think that is what I'm going to do.

 

1/3 the price $215 vs $62x

 

If I was going to use 17" wheels I'd choose the SSR Type C-RS for a very specific reason over all the other 17" wheels. Now ask yourself why that is?

A. Team always buys the most expensive parts - wrong
B. Team is an idiot - high probability
C. Team figured out something nobody else did yet - most likely

let the Engrish lesson begin:

best = best

affordable = affordable

cheap = cheap

 

Yeah guys, weight isnt everything. The RPF1's will have more flex and will be less ridgid than the SSR's.

 

Or because you're a good enough driver that having the best wheels will matter in your raw times. . . someone like myself who hasn't even done 10 autocrosses total and is on a limited budget probably shouldn't blow my season's budget on wheels alone.

Although they'll hold their value and can be sold pretty easily, I'd still rather go with a budget, lightweight cast wheel until I get better.

I know that my specific viewpoint isn't what you were addressing, but where you are in your skill level and your goals for autocross are very important considerations to make.

 

I have a different guess based on the fact that the SSR is the only non-custom 17x9 that I know of available in a +55 offset.

Scrub radius. This was alluded to in an earlier (now deleted) post. Moving the wheel centerline in will cancel out the increase in scrub radius caused by the 0.9" smaller diameter tires. I don't know the RX-8's nominal kingpin inclination, but if you wanted the point where the steering axis intersects the ground to be the same as stock, it would be something like 23 degrees, which is ridiculous. Assuming it's much lower than that (3-5 degrees?), you start inching the center of the contact patch closer to the steering axis, which can actually significantly reduce toe-out under braking and improve your corner entry characteristics. In fact, if you can move the tire patch in far enough (maybe with the 949 Racing 17x9 +63 and a bunch of camber?) you can even induce some toe-in under braking to give you an oversteer characteristic...

My other much more far-fetched guess is that when you have too little offset, the caster effects will lift the front end when you steer, causing an understeer condition. But like I said, I don't think that's actually it.

Am I on the right track here?

 

You're cold ....
