Good rims for Stock Class on a GT

[nullsurfer]

Well shazbot,
I need a set of rims for my 02 GT. They need meet the solo rules. I have 2 sets of rims aside from the steel wheels that came on the car. 1 set is 1/2 an inch to wide. And I just found out the other has .5 inch offset difference from the stock.

I need cheap, but also wouldn't mind light. Good looks would be a triple bonus.

Assuming you mean wheels for *stock* class rules, the best value appears to be the Rage Race 10 and Rage 5.0 wheels from Discound Tire (www.tires.com).

Both weigh in at about 16 pounds, come in a 15x6.5 and a 38mm offset.

It might be possible to use the Rage 5.0 with the stock lug nuts (it is NOT a 10 hole wheel). The other advantage of the Rage 5.0 is that it is much easier to figure out which holes to use.

OEM alloys can also be found for cheap on Ebay (sometimes), those weigh in at 17 pounds.

I beleive some of the stock people on here are running the Rage 5.0 cheap and relatively light and in the classic five spoke design too. I think AutXr has them, PM him for more specifics.

[Celica RZ]

oops! looks like he got here already :D

What about putting in a spacer? The stock offset is 45mm and the rims I have are 35mm.

[Celica RZ]

stock offset is 39mm

[nullsurfer]

Kurt from Tire Rack said 45mm. Hmm then I don't have to worry.

[autxr]

Kurt from The Tire Rack was wrong, stock offset is 39mm, as stamped on all of my OEM alloys.

Your 35mm offset will be fine, and likely a bit better (wider track).

You will be good to go if the ones you have are 15x6.5 inches.

15x6.5's are what I got. I was very careful about that.

Whew!
:AF: :wiggle: ;) :cool: :wave: :applaud: :thumbup: :bowdown: :rofl:

[nullsurfer]

Where can I find documentation to that fact? (the 39mm)

[autxr]

Don't know about the documentation, but I assure you it is 39mm. I can take a picture of the stamping on the stock alloy wheel if you want.

It is an interesting dilemma

Scott

I can back up that 39mm stock offset, as my primary auto-x wheels are 15x6.5 BBS's with a 33mm offset. Can't get much closer to the allowed 1/4" per corner than that. :D

I'm sure as often as I was ahead of Mr. Chiles last year, someone known to be particularly fussy about his competitor's wheels, I would have been tossed out on my ass DSQ/DFL if these were the least bit bogus.

[nullsurfer]

I went to the dealership and NO ONE could figure out where to find the offset. Pitiful. Anyway, I will just plug away until someone complains.

Thanks

[nxracer]

Trust us! the stock offset is 39

Rota wheels are worth a look...I checked some out when I was looking, but couldn't find anyone with enough details. They're generally pretty light, they seem to have quite a few 15x6.5, 5x100 choices and they're reasonably priced.

Hey PerparedCivic, watch those 33mm offsets... To my calculation that gets you only .63 of 1 millimeter in tolerance. Difference in atmospheric (sp) pressures might make your wheels illegal....

Just because Chiles is out of the class doesn't mean anything..... :)

Seriously though, I tried to find some .33's and ended up with my .35's...

Since you used to be in a position of rules making/interpretation pwoer....

If there was a protest on wheels, would you go by what was stamped in the aftermarket wheel, or actually measure? What kind of tollerance would you give the manufacturer on stamping? Say it was a .325 mm offset, they might round up, but be illegal for what we are doing?

Well to start off with I'm not an official anything this year, as of 12:01am January 1st. My first year since 1993 without a SCCA title. Yippie! :applaud:

As for wheel offset protests, It is an easy verification measurement to take, so chances are the protest committee handling things would dismount a tire and measure the wheel(s) in question.

Think about it a little bit though, it would be really hard to decrease offset on a wheel without adding material to the hub face. I would say with my 33"s for example, which are 7 years old and have 60k VW street miles on them before becoming Celica auto-x wheels, that the hub face is if anything worn and measures a few thousanths more than the cast in spec dimension. The more material off the hub face, the more the offset will be.

I'm not worried that my BBS's, cast and machined by anal sour-krauts, and owned by me since they were shipped from The Tire Rack, are anything but dimensionally accurate.

[ConeKiller]

I guess my question would be how much tolerance would the SEB give on an appeal, when the casting says X but the measurement is actually 1 mm off.

It would not make any difference on course, but I guess my opinion is that's why they give you +-5mm.

On the other hand, most of us take for granted the number spec'd from the manufacturer.

Rick

[preparedcivic]

That's an easy common-sensical answer.

Our spec is 39mm, the 1/4" +/- =25.4mm/4=6.35mm +/- tolerance.

Therefore, anyone with a 2000+ Celica GT better have wheels that measure out at an offet ranging from 32.65mm to 45.35mm, no matter what is stamped or cast on the wheel.

[ASM]

So,

Knowing the "Stamped Offset" is so inaccurate. There is really no particalar reason why Toyota choose 39mm as the offset for Celica, right?

I am in the process of buy a set of rims, not for Auto-X, only for street. The wheel I am trying to get is Racing Hart Z5000 and it only come in 34mm and 40mm. The shop insist it's better off to go with 34mm. But I am not so sure...

I know for sure it will provide wider track, but since now the wheel is further out away from the struct, wouldn't it more likely to push the struct up (buttom out).

[nxracer]

I would guess (you don't say) that your new wheels are something like 15x7 (not 15x6.5) If this is the case the shop is correct and a 34mm is what you want.

[nullsurfer]

Thanks for the help.:cool:

[NoCones]

why would you want 34mm offset just because the wheel is a half inch wider? I would want to retain as close to stock offset as possible (for the street anyway).

With 34mm, the outside of your wheel will be 5mm + 0.25" (almost 1/2") further outboard than OEM.

With 40mm, the outside of your wheel will be 0.25" - 1mm (slightly less than 1/4") further outboard than OEM.

As long as the extra width doesn't cause rubbing on the inside of the wheel (and I don't think 1/2" will), I'd stick close to stock offset.
