Hey guys, tried searching for this and came up with everything but what I'm looking for. I have an 07 STR and wondered what the factory wheel specs are front and rear? I know front is 18x8.5 and rear is 18x10 but what are the offsets?

 

standard fitment for your car is

2007 S-TYPE R (Front) 245/40ZR18 Vulcan 18x8
(Rear) 275/35HR18 Vulcan 18x9.5
2007 S-TYPE R 275/30HR19 Optional Barcelona 19x8

 

Stock offsets are +60 front and rear... yea very high positive offset. Very few aftermarket wheels will fit. In the cases where they do, theyre 8" wide pizza cutters with ET45.

 

Or you have run spacers (the Convertrys) or go with custom wheels ($$$$)

 

Spacers will only make make not-positive-enough offset situations worse. Spacers may be necessary for brake caliper clearance issues on our cars.

 

or you search wheels sights for weeks and weeks and make some calls and have everyone tell you nope... those will not fit....and you decide to have your stock wheels painted a custom color and just lower the car because custom wheels and tires are 1/2 as much as the car is worth......oh that's right i did that.......trying to find a aftermarket staggered set that works is near im possible... about the only choice that is reasonable is the Forgstars...

 

Ya sorry that is what I was implying. Damn Brembos...

 

I dont know if this will help but Staggered Caravelas will fit the STR. I have an 05 with the stag caravelas on it. Caravellas came on the new generation of Jags, XFR, XJR, XKR.

 

>Stock offsets are +60 front and rear

I'm shopping for wheels and have looked at Tire Rack who reports that the offset is 48mm.

Depends on which model S-type you have. Remember, the offset number relates to the width of the wheel, so you can't compared offset figures directly across different wheel widths.


The STR staggered fitment 18x8 and 18x9 setup is +60 front and rear...

Ah, I did not know that. Thanks for the clue

I'm planning on purchasing a set of Forgestar F14's. They are custom made to order and have an aggressive offset. I have been talking to GT42R on this subject and he has no issues with clearance or rubbing. Not sure what's different from the 03 to 07 besides calipers. Also will be lowering the car with H&R springs.

 

the Forgstar guys are familiar with the STR and will set you up with the correct fitment..

 

CCW, is another option besides forgestar. Better quality imho and very light, I'm running ccw c2k's 18x8.5 front and 18x9.5 rear with slightly lower than factory offset and factory size Bridgestone So4 rubber. Also lowered on H&R with zero rubbing issues

 

They are also twice the price. I haven't heard about quality issues with Forgestar, what am I missing? Any reason you stuck with 18s instead of going to 19s?

 

Wanted to keep what little sidewall was there. Also wanted to not add any extra unsprung weight to the corners as this car gets the occasional track day and regular hard driving and the ccw wheels actually reduced that as they are lighter than factory
Google forgestar wheel faliure then google ccw wheel faliure... if the Internet has proven to be one thing it's a place where people come to complain about bad experiences, there's lots of complaining about forgestar. There's a reason they are so cheap, you get what you pay for with wheels. Not saying they are bad, just seems to be quite a few problems

 

Damn, CCW's on your STR? gotta post pics! Although if I was going to put custom made wheels on an STR, it would have to be one size up 19"... 18" just too small... and it's an STR, more of a cruiser, so all out performance isn't the focus for me personally.

CCW makes some of the highest quality wheels I've seen, but you pay for it!

Personally, I can't complain about the quality of my forgestars, fairly lightweight too, and the price is great.

Most of the complains I've seen related to production lead-times... If you dig long enough, you'll find alleged quality issues with almost any custom wheel...

 

You can also check ebay and other wheel sites. There's quite a few aftermarket wheels being made for the xf and new xj that would fit our cars.

 

So I'm not a wheel expert by any means. Offset yadda yadda is greek to me. I've always gone to the wheel shop and bought wheels and hub centric rings.

Saying that to say this, CarId.com has a large selection of wheels that "supposedly" will fit an 07 STR. I know that in the past I was looking for a different set of wheels for my car and if they did not fit, a message would appear saying so.

Is carid blowing smoke?

I also thought I read on here a while back that TSW makes Coventry wheels. If that is so, there are a lot of TSW wheels available.

 

They're not blowing smoke, they're just not selling you the same wheel you have on atm.

All of the ones I can find that carID is showing are 8.5" wide, the stock rears on the STR are 9.5" wide, by dropping an inch of width you can fit a lower offset wheel. 1 inch is about 24mm so you could fit an 8.5 ET 36 in place of the 9.5 ET 60. However good luck getting that 275mm tyre back on.
