YES..my car is an original GSL-SE. I installed RE-Speed's big brake kit both Front and Rear (complete with Moser axles) with TII calipers and disc all around. The offset did NOT change with the conversion as everything still is pretty much in stock location. As stated, the rear wheels do stick out about 2mm but with stretched tires it is a good fit. The front fit fine with the setup on it now, they are flush with the fenders. All 4 fenders have been rolled for better clearance.

On another note... I had 0 offset Panasports that I tried on the car prior to my 5-lug conversion and they stick out past the fenders on a true GSL-SE. It has been discussed on here before and 0 offset's will NOT work on a GSL-SE. They will work on all other FB's.

Keep the ideas coming.

So what was ever decided, RotaryRevn? I am DYING DYING DYING to know if 15"x7" 0 offset wheels will work on my all stock SE withough rubbing/rolling/ or other mods... Can someone PLEASE clarify this for me once and for all?!?!?!?!?

thunkrd 10-11-10 09:21 PM

it will rub on a stock gslse 15x7 +10 rubs with 205 50 15... even with rolled fenders

jshiz 10-11-10 09:28 PM

I'd imagine. Even though my car is lowered, a 14x6.5 with -10 offset rubber the fenders.

?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????Sorry, but 100% NONrelevant! So the definative answer is NO? Do I have this correct, please from someone who actually tried it themselves? If not, what is the correct answer for this thread assuming a 15"x7" wheel?

Thank You! But what about 0 offset?

There is no way 15x7 with zero offset will work on a gsl-se without sticking past the fenders. I have tried it and didn't care for the look.

I don't have the perfect offset figured out yet but I do have a set of 16x7 +25 and 16x8 +26 but I don't have time to test fit them just yet.

I have a strong feeling 15x7 +25 is about as low as you can go on a 7" wheel without the wheels coming past the fenders. Hopefully one day we will get to the bottom of this discussion once and for all.

If you didn't lower your car, they might not rub but they would stick past the fender.

jshiz 10-12-10 05:57 AM

15x7 +20 should fit nicely

HadaGSL-SE 10-12-10 08:33 AM

I just put on a set of 15X8 with a +15 offset. They stick out just a tad but should work. My fenders are rolled. I would imagine with an 8 inch wheel a + 20 would be ideal.

sevens4me 10-12-10 09:09 AM

Allright, thanks for the relevant input, guys. So if I got this right, a positive 20 or 25 would be about the limit for an all stock SE. Forgive my ignorance, I've been searching, that's why I brought this thread back, but the more positive in offset you go, the more "clearance" you'll get at the fenders, correct? Thanks again.

jshiz 10-12-10 10:14 AM

i'll make it simple. offset is the location of the hub to the wheel. 0 offset would put the hub directly in the middle of the wheel. make the number higher, the hub/face of the wheel will move forward. negative offset will do the opposite. the effects of offset wilk change depending on the width of the wheel. that's why most serious people will opt to use backspacing.

backspace is the distance of the hub to the back edge of the wheel. so nomatter how wide the wheel is, the backspace will stay cobstant.

they each have their own uses.

Let me add a little to my previous response. I'm figuring that 15x7 +25 would work with rolled fenders and no wider than 195 tires (on a lowered vehicle). Of course could go a couple of offset either way. Even different brands of tires of the same size have a different "buldge" on the sidewall. Some sidewalls are straighter than others.

I think my fins are APPROX. +33 with 195 tires and if I didn't have the negative camber up front, and if the car was lower, I think they would be close to rubbing in the front (my fenders aren't rolled yet).

Yes the more positive offset, it brings the wheels in more giving more clearance between the outer edge of the wheel and the fender. Keep in mind that if you go too positive, you could have clearance issues on the inside. This becomes even more important when fitting wider than 7 inch wheels. You need to find just the right balance for your taste.

These are the 15X8 +15 offset for your reference.

how much clearance do you have on the inside of the wheel? from what i have read, the ideal back spacing is 4.5 inches for the SE's. on a 8" width that comes out to zero. with +15 offset, thats at least a 5" back spacing. my biggest concern is the inside of the wheel will rub on the suspension Springs. i currently run ground control coilovers. i had 17x7 with a 40mm offset which fit fine with my stock springs but when i switched to coilovers, the same wheels were rubbing with the springs on the inside of the rim. the reason i am asking is, i am doing the BBK kit which changes my bold pattern to a 5x114. i picked up some mustang gt wheels (17x8 +49 offset), the offsets are a bit high. i am trying to figure out how big of a wheel spacer i will need to make them work. any help will greatly appreciated. thanks.

hoang

your car looks awesome by the way!!!!

HadaGSL-SE 10-13-10 06:07 PM

Thanks I like it.

I am running Re Speed Coilovers in the front and have just about one inch (maybe 3/4") in the front.

Close to 2 inches in the rear.

I am much more worried about rubbing the fenders than the springs right now. Initial test drive revealed no rubs but the next autocross might prove me wrong.

Looks the goods mate! from your experience with these wheels, do you think 15x8 +25 would fit on the front with the stock spring seats? my s1 is lowered 2" front and rear if that helps...

HadaGSL-SE 10-14-10 08:05 AM

+25 would be 10mm closer which equals 3/8 of an inch.

It should work but will probably depend on the tire you run. Mine are 205/50/15 Hankook Ventus Road Racing Tires that came with the wheels. I drove it around last night and didnt have any problems.

I spy a spark yellow back there in the garage Greg. How's it going? Does sparky live?

Sorry for the thread jack.

I honestly have not touched her since I got home. I ordered a bunch of tune up parts but haven't really done much of anything.

This guy (5.0 Miata) dominated almost all my time. We ran it at the Grassroots Challenge two weekends ago.
