I have a 94 gsr, its dropped with eibach pro kits and bilstein shocks.

Im looking at getting some 15" Rota Circuit 8s off groupbuy. The webpage says 38mm offset only.

How do I know if that will be fine? Actually, I'm not really looking for a technical answer, I would just like someone to say "hey mike, those circuit 8s will be fine on your car", or "hey mike, those circuit 8s will not work with your setup".

I currently have the stock gsr wheels (94 5-spoke) with 205/50/15 rubbers, and I was planning to get those circuit 8s with some new 205/50/15 rubbers too. Is that the right size tire? The stock wheels are 15x6 and those circuit 8s are 15x6.5. I'm pretty set on getting the kumho 712s.

here's the url for the wheels http://www.groupbuycenter.com/buy.asp?row_id=2765

PS. yes, i searched, i cant find the exact, specific answer im looking for. i apologize for making an extra post, but would hate to spend $500 and have the wheels rub or whatever. thanks

I had this saved from vtec.net web page: (it's kind of technical but you can make your decision based on it)

"Generally, if you increase the width of the wheel by 0.5", you want to subtract 0.5"/2 x 25.4mm/inch or about 6mm offset. This perserves the intended wheel geometry. However, there are some limitations, due to interference with the shape of the fenders and possibly other components:

From: Wisrute Buddhari (wbuddhri@uop.edu)
Warning: For those who are looking for rims for your (lowered) Integra, try to stay away from anything wider than 7 inch with 35mm offset (use 38-40mm), or your tires may rub the fenders! Stick with 205 tires, if you want to go real low."

Since the stock wheels for the 94+ Integras are 15 x 6.0 with 45mm offset: 45-6=39mm

Try also sites like tirerack.com, they must have info on wheel sizing, etc.

[/b]Mike:[/b] The 38mm offset ought to work fine.

I believe I read at http://integra.vtec.net that 38mm offset is ideal for 7" wide wheels. Since stock offset is 45mm with the 6" wide wheels, 38mm offset for the 6.5" wide Rota's should be alright. My 16" x 7" TSW's have a 40mm offset, and no problems.

Basically, what I'm saying is that the 38mm offset for your Rota's will be fine and look great.

Thanks for the info guys!



Thats the answer I was looking for, I'm in the middle of learning all this crap for these certifications, and i'm working at a new job, and my brain is near capacity at the moment. I really didn't want to have to apply a whole lot of brain power to decide if these wheels would work or not.

I would also feel bad if Teken spent 2 hours writing a 5 page description of wheel offset Besides there's plenty of info about offset, I just wanted to be sure they wouldn't conflict with my spring setup.

thanks!

let me give you some simple friendly advice...
if you get bored one day, grab a pencil, paper and a ruler (pref. metric)
draw a cross sectional view of the stock wheel. Draw a line drawing out to scale 10:1 using the stock rim width and offset (6"= 152.4mm for the width) and (45mm for the offset). If you didn't already know the offset is the distance the mounting surface is from the exact center of the rim. Then go online and see if you can find the specs for other aftermarket rims and then draw them out too. This way you can then hold one sheet over the other and compare. I did this myself on AutoCAD and it helped when i could actually see the difference between the different models.

I've been enjoying it the whole time

Only thing left to do is repaint it...

Unless... I get that new position opening up next year... if so that means

2 x "current salary" = rebuild and JRSC
