The fronts fits about perfect, and without fender mods, I don't think you will get more. These are 30mm Offset.... |
Kent - sorry, but those 18x10.5" ET30 Enkei NT01+M's don't fit on either end with anything close to perfection, at least to my standards. The poor lighting and odd angle on those pictures you posted (especially from the back) don't really show the situation clearly. Costas and I looked at your car and those very wheels & tires in person at the National Tour event 2 weeks ago and both the front and rear tires stick out past the fenders. A
lot out back. Sure, "it works" for autocrossing and is common for the category, I'll grant you, but its not what I'm looking for. Madderash's F-Body wheels stick out as well.
Left: 18x10.5" ET38 (7.2" backspacing) fits up front - BARELY. Right: Same wheel on back sticks out a ton
As you can see above, we've fit an 18x10.5" ET38 (another 8mm inboard than Kent's) on our car with little 285s and they
just barely cleared in front but stuck way out in the rear. These have a measured 7.2" of backspacing and have about 3mm of room inboard to the AST strut. Not any room to be gained up front, so nothing wider would "fit" in my book, without flared fenders.
The rear on this 18x10.5" ET38 wasn't even close to fitting - it stuck out more than 1/2" - and this is why I'm
still somewhat curious how an 18x10 with the same 7.2" backspacing would fit really well. The rears need to go inboard another inch, if not 1.5". As you can see in the picture above, right, there's a good "three fingers" of clearance inboard to the unibody with these 10.5" (7.2" B.S.) wheels on back. Using something like an ET60 would be a good place to start (8.1" of backspacing). But then you'd need a good sized spacer up front (nearly an inch thick) to have a set of wheels that rotate easily (and yes, ideally I'd want that - as would most track guys). That's a lot of spacer, so realistically a rotatable set of 18x10.5" wheels isn't possible... but an 18x10" set is.
For a properly fitting 18x10" set, in my eyes, I'd want to have the front
end up at 7.2" backspacing, but I'd be happier with 7.5" B.S. on the rear, or a 10.5" with 8.0". So I might (if I have to go custom) build an 18x10" to 7.5" B.S. and use a ~1/4" spacer up front. That's if I have to resort to a custom set (CCW). Don't know yet... still looking at some Porsche rear wheels...
Good news on the 18x9" wheel search, thanks to BRODA's suggestion about the WedSport. Found one of our dealers that had a set in stock and they made us a significant;y better deal than $620 each, so a set is incoming. This will be for autocross use (only) for the 265/35/18 Toyo R1Rs. They
claim to be 16.9 lbs but I'll snap a shot on the scale and post it up when they arrive, next week. For reference here's a Speedline C5 Z06 1
7x9.5" wheel that Costas brought by and we weighed today. Not bad for an OEM wheel, but Speedline is very weight conscious.
Also as you can see above, we have the Mustang torn apart awaiting more parts. New rotors and Hawk HP+ pads are going on and the front struts are being revalved at AST-USA today. Trying some new spring rates and I'll report back how they work in a little over a week (two autocrosses that weekend). Also, we weighed the stock front and rear rotors, which can be seen below.
Wow. The front rotor weighs more than the wheel. That's... just, wow. And no, we're not paying $800 for the 2-piece Girodisc rotors that are on the market, but we will be doing something about that. I bet there's 10 pounds in the front rotors alone that could be lose. The hat section of the stock front rotor is THICK steel.

Yea, the CCWs are definitely on my short list for the 18x10" wheel set that we need for track use.
I've had many sets of the 3-piece CCW Classics ($575) but the 1-piece monoblock CCWs look intriguing as well ($700 each). If I keep striking out on a 1-piece wheel that fits correctly (and hopefully at a lower cost), then I'll call CCW back once again.
More next time...
