FC wheel offset
 

What kind of offset are you guys running with 8" or 9" wheels. I don't want to add flares if I don't need to.

Thanks

I've got Keizer 15x8 wheels with 5.25" backspace. In the front I have to run a 1/4" spacer so the 225s clear the coilovers.

+40 with a 20mm spacer all around 8.5" rims. VERY Mild baseball bat flare in the front just rolled the lip in the rear.

my street car runs 8" rims at +25, no flare, just rolled lips.

I run 225/45-17 tires on a 8.5" wide 42mm offset rims front and rear. In the front I have a 17mm spacer/adapter and rolled lips. In the rear I have a 22mm spacer/adapter and stock lips. This is with stock style struts/shocks - I have not yet installed the coil-overs.

I should mention i run 225 or 235 tires depending on brand...

Thanks guys!

We currently run 225's on 15x7. Want to step up to and 8" or wider rim

Any suggestion on rims?

finding a low offset 15x7" or 8" rim has been nearly impossible for me. There are used kosei's around but hard to find...ive been trying to get a price on some team dynamics pro race 1.2 in either an ET15 or ET20 but no luck as yet.

its easier in 17" to get a low offset bot not super easy, i have been running the 40ET RPF1 with the spaces simply because they are plentiful

I couldn't find any off the shelf 15x8s that fit under the stock fenders, so I wound up having wheels made. I went with Keizer, but any number of companies can do it. The trick is the amount of time it takes to get them. I cancelled orders with both Spin Werks and Jongbloed before ordering from Keizer -- the other companies were taking too long. And even with Keizer a while.

MRW can make me steel 15x8 NASCAR style wheels at $70 each but 19lb the Ultra Stars

I can put you in contact with a friend of mine that imports TD PR 1.2 rims. Send me a PM if you are still interested. I got a quote from him on 17 x 7.5" TD PR 1.2 with the correct offset for the FC RX7 before deciding to go with the wider and lighter weight 17 x 8.5" SSR type C rims (which required adapters).

I would also recommend 17" RPF1 because it would be much easier - just not sure if your chassis setup will work the same with a 17" as it does with the current 15" combo.

Diamond Racing Wheels will also build them, I think for about the same price.

Steel is always an option. Not one i am crazy about, but cheap and easy to come by.

I'll share my recent experience. Earlier this year, I spent a lot of time researching availability of low offset 15" wheels, off-the-shelf. The selection is very limited for the 5x114.3 bolt pattern. In the 7" width, the only choices (with <40 offset) are:

Panasport +0 offset
Spinwerks +0 offset
Team Dynamics +35 offset

I spent 2-3 months waiting on an order of Team Dynamics Pro Race 1.2, +23 offset, which they claimed were on the shelf somewhere in England. Ultimately they admitted they were NLA and no plans to make any. The Pro Race 2 is discontinued.

The Panasports and Spinwerks are > $200 each. The TD is $135.

(For 4x100, the selection is much better -- 15x8s and 15x9s can be found in that BP).

If you can run 17", I have 17x8 SSRs +40 offset, and 5Zigen FN01-RC 17x9s, +15 front, +35 rear. The +15s require the 20mm fiberglass fenders from Mazdatrix (or flares).

Had to order mine and it took 2-3 months but was able to get 12 of them for $1800. They will make our pattern in an ET15 (lowest they can go) but you have to wait, normal production is ET35. Ask a local mechanic shop to order for you from TD. The shop I used is out of business but was just a local general repair shop, just need to be in the auto business somehow. Not sure on the markup but am guessing they did cost + 10 or 15% was all. My hookup at Discount Tire used to do the same before he stopped working there.

I will probably end up going SSR and keeping my 20mm spacers if i switch to 15" rims. But, boy are they pricey for 15" race rims. They are only made in +42.
