Thumbs up Yes!!! the possibility of STi with 16" fitting over brembos!

I have just faxed my Purchase order yesterday to Motorsports Specialties in PA(www.usacomp.com), the distributors of Compomotive (made in England, www.compomotive.com) wheels here in US. Allen Paxton and I spoke and Compomotive UK is currently in design engineering review this week and strongly considering slight modifications to their 16" * 7" version casting molds of the TH3 "run-flat wheels with the appropriate 48-50 mm offset range we need. The full intent will be for a strong, light weight 16" wheel to bolt on for winter use over the brembos with no mods.

I was the second person to place an order for 5 silver colored wheels per this information. Each wheel cost $310.00 +shipping Someone else in Montana seems to be the first. As others like Janq have noted, these wheels are the real deal for strength and reliability. If rally racers can trust them.....so can we.

Contact Allen Paxton or Belinda at Motorsports Specialties if you are interested or willing to fax in an order. (800-621-8408 phone, 717-786-3496 fax)

I plan on then ordering a set of 5 205 55 16 VR rated Dunlop Winter Sport M3 (Runflat variety). (see www.tirerack.com)

This should make for excellent fun!!!! and a little more rubber between me and the road on upcoming Michigan TSD rally events and SCCA Prorally event working.

I will keep everybody posted.......do I sense a possible group buy coming from those that live in the snowbelt or mountains??????

the measurement from the center line of the hub to the top of the caliper is almost 7.5" ..... I seriously doubt that any 16" wheel would have a 15" inside diameter with todays wheel manufacturing technology

Im not doubting that it could be possible, but beware that the 48-50mm offset might turn into something like 40mm. Thats what I found when researching small wheels that are claimed to fit over large brakes...

just a side note....

when searching for wheels remember to look beyond the offset... w/ the your beautiful brembo brakes... spoke design comes into play.

example:

17" Rota Downshift
Width: 7.5
Offset: 48
STI Fitment: Negative

17" Rota SDR
Width: 7.5
Offset: 48
STI Fitment: Yes

if it does fit... great find!

...the 40$ saving per tire doesn't seem to offset the $100+ per wheel to get the one and only 16" wheel.

For that money I'll take the 17in Tarmac II's with 225/50/17's!


BTW a 205/55's gives you 4.44 inches of rubber.
The 225/50's give you 4.43...practically the same!

So if it comes down to the same amount of rubber cushion I'll take the 17'...especially since I can use the same rims in the summer for track tires.

I think you math is wrong ...

I get

205/55-16 = 4.4389763" sidewall height
225/45-17 = 3.9862204" sidewall height

He was using a 225/50 not a 225/45, however the 225/45 is what one would use if they didn't want to screw up thier speedometer. Running a quick calc I get 4.19 for a 225/50 by adding 5% to Luke's second number.

Thanks.

Actually, I have no problem "screwing up" the speedo in favour of less milage accumulated per actual milage travelled.

Stock diam 24.97" 0.0%
225/50 25.86" +1.036%
205/55 24.88 -1.004%

...225/50/17's will provide 4% extra milage for free. Plus, since traction is lower with winter tires and cold surfaces in general a slight wheel torque reduction is not gona do any harm.

Spoke design on the TH3-if you went to the web site- is much different that Rotas. Indeed, you would find http://www.usacomp.com/Competition.htm 15 spokes and a much more closed design. More protective of those precious brembos we own!. Better also for the snow and reducing wheel snow pack. Al Paxton called today to acknowledge order receipt and that it was forwarded to Comp UK. He will have daily word to me starting Monday regarding progress. I don't want to ring the bell before dinner, but concerns over whether Compomotive would get this 16" right are overblown. They have to stellar of a reputation to say yes to a project and then screw it up with a missed offset calculation....... We shall see.

Default Re: Yes!!! the possibility of STi with 16" fitting over brembos!

I was the first customer in the US to
purchase a set of TH3's 17x7.5 w/ 53mm offset. I just put the wheels on last night & I can tell you that there is
no way a 16" wheel will fit no matter what offset. The radial clearance over the caliper requires the use of a 17" wheel diameter minimum. BTW, the car looks awesome with the wheels & tires, like I'm ready to start the first stage of Rally Finland!

Just an FYI, the radial clearance is so tight w/ the 17's that I worked w/ the tire guy and put the wheel weights in particular places because the clearance near the outside edge over the caliper is that tight.

Yea this is going to be amazing if at all possible. It is almost unfathomable to me a set of 16s fitting over the Brembos.

Please keep us posted.

interested to see if this is possable...
after laying on my back for 15 mi with my tape measure....
initial rough estimates tell me that if it is possable........... it would be tight as H.E. doubble hockeysticks....


still would be nice to get those 16" gravel wheels someday....

I just called Allen and he said they are about three days from receiving whet theh ordered to test. At the same time I asked him about 15'' fitment for the rear Brembos and he said he will try to check it. If 15'' would fit I'd get them because there are a lot of nice and cheep tires (for snow and for gravel) in 15'' when the only gravel tire in 16'' I found is quite expensive Michelin ($140/piece). I can get a new front brake set like 4-pot Subaru kit for about $700-800 and changing the front is not so bad but I would not want to change the rears cause it's a major pain.

Evo's brakes, STI brakes, apples, oranges.........

And you want to put 15" wheels on the back and 16" on the front of your STI? I hope you typed wrong.

You buy a 30,000 car and complain about tire prices.........

Rough crowd.

I personally wouldn't be surprised to see a 16" come out, though.
I mean, the Raceline RL-7 in a 15" fit over the old four-pot STi brakes, as well as several much larger brake kits.... And that was just their 15" model...

I know it seems impossible, but "you never know" is all I'm saying.

Both are big. And they have even the same calipers I heard.

You read it wrong. I prefer 15''s all around.

If I can get 15''s and buy tires a lot cheaper, have more choices and more safety on rough stuff with higher sidewall I want it. If I can not fit 15''s over the rear Brembos (I can change the front brakes but I'd rather not touch rears) I'd get 16''s.

On the stock BBS wheels the inside diameter is about 15" and that seems to be about the minimum inside diameter that will fit over the Brembos.

So if I understand this right, Compomotive is making a 16x7 wheel with a 15" inside diameter?.

STI rammer / mtcossie, it's been a couple of weeks since we heard anything, are you still waiting for your wheels?
