Running STX in my SS/TC this year and I'm about to order wheels and tires. I'm looking to go 17x9s with 255s but I'm unsure of offset. I saw there was quite a bit of 'poke' in the rear with +35 so I was thinking +40 with a 5mm front spacer. Would they clear the brembos without the spacer? Ill be running the federal rsr959 in 255/40r17 at first because of the cost benefit and going ***** out on tires next year. I will probably be running YYZs and koni yellows by late in the season but first priorities are tires and a sway bar.

Help is much appreciated. And if anyone knows a vendor I could contact about this I would appreciate that too.

Search it via google you may find it

You can get different offsets front and rear. Just sayin'

I ordered a second set a couple weeks ago. I have been using Team Illuminata.

jboogie ran +30 front and rear, because they had those in stock. I'm running +30 front +45 rear. I'm not sure where you saw someone try +35. With a 255, strut clearance gets pretty tight. I'm not sure that you run more than +30 to be honest. Probably with coilovers.

Throw up some pics ... Spacer needed ?

GR1VLET

I really need to be able to rotate the tires front to rear to get more life out of them. Fronts will wear much faster in a fwd car. I thought I saw someone running +35 but I could be mistaken. Then maybe I would run +35s with a 5 mm front spacer. No rotate, no deal.

I have some pictures floating around. The purpose of buying these wheels, at least for me, is to take advantage of them being able to machine whatever offset you want so you don't need to use spacers.


meh. just run the stock wheels, unless there's an autocross coming up. It's also possible to buy only two tires at a time.

just clear it up, ... you are running +30 up front with Brembos on an 18in wheel ?

Hi Ron,

*

Nice to talk to you this afternoon. Thanks for calling.

*

Just to confirm, I think your approach is very practical and should work just fine. Go with the longer studs though. You can always cut them down. 255 tire should be fine on 9” rims as should a 225.

*

Specs on these will be:

*

Wheel model:* Pro Race 1.2

Size:* 17x9

Offset:* +45

Color:* TBD

Hub Centric Bore:* 65.1

Bolt Circle:* 5x110

Lug Style: conical (OE I think)

*

Price is $238 each plus shipping from California. I should have asked for your zip code when you called. Oops.

*

Delivery in about 8-12 weeks.

*

We have sold 7 sets of these to six Cobalt SS owners. Most have gone 30/45 but a few have bought+30 all round. Don’t know what tires they are running however.

*

Let me know if you need any more information before ordering.

^^ straight from the man himself. He said they run spacers on the rear of their 911 race cars for this very reason. OUTSTANDING cust service by the way.

Next question - extended studs - ive heard the arp are too short, but the gmpp ones are expensive. Gotta pay to play, I know - but I'm trying to be as frugal as possible.

Team Dynamics Pro Race 1.2 wheels in 17x9 +30





I think I found the wheels I'm gonna get. So what would make the front and back offset have similar "poke"? They clear the Brembos fine?

I like those

+30 front is what you need for fender/brembo/strut clearance.
+45 rear is what keeps the rear tire within the confines of the rear fender.

I plan to run +45 all around with a 15mm spacer up front on gmpp extended studs. This will allow you to rotate the tires for longevity. You can do +45 rear amd +30 front, but without the ability to rotate expect to replace a lot of front tires. Since I want even wear on all 4 corners I need to be able to rotate. As the TD guy stated - they run 20mm spacers on their Porsche 911 race cars for that reason.


+30 all around is do-able but it could lead to fender/tire interferance in extreme circumstance. On a lowered car the +45 will be a must, but inner fender/ tore clearance may be an issue. I plan on running YYZ v1s or maybe v2s. I'll have to load the car down on stock springs and see what happens.

Also, I'm grivlet from jalopnik! Nice to see ya again!

Thanks. Now to save money. 17" Summers and gonna have 18" Winters.

Seems like me and you take every opportunity to bring up the TC on Jalopnik. People need to know how great these cars are.

I like how people continue posting like they are unsure about what offsets will work. This stuff was proven years ago. There are countless threads about it.

cluelessk

There is not a lot of info online. And confirming always helps. I always double, triple check everything especially before a big purchase.

Well some people don't live on the forums - plus I am trying something new and I want to share my thoughts/experiences as I do so. Some people don't like spacers but the truth of the matter is that with a hub centric spacer like the H&R there is nothing to worry about, and countless people run spacers on dedicated race cars so they can rotate and extend tire life. If your not comfortable with them - then definately do not run them since anything that affects your confidence will slow you down.

I'm with cluelessk - when googling all I found was Jboogies setup, and +30 all around is not what I want for clearance reasons and staggered wheels are impractical for what is nearly a dedicated race car.

Has anyone considered a group buy of these things instead of the RPF1's? that group buy seems to be DOA, and it was going down the 18x8 road. Someone should contact them and ask.

Side note, how heavy are these wheels?

GR1VLET

While the wheels are 21lbs/each in a 17x9, they are STOUT!

Wheels are the spec wheel for the British Touring Car Championship and have been for several years (in centerlock configuration).

Ive been in touch with the guys at team illuminata - they may be willing to do a group buy. I can ask. There is an 8-12 week lead time simce they are custom drilled in the UK.

Wheels were 238/ea in 17x9

Wish I had money for em. Would order me some white ones but life comes first.
