I feel like a moron, but I'm just not getting it. Here's why I'd like to find. A used set of wheels, that aren't OEM to be used at the local autox club. My only requirements would be the exact same size as stock and lighter in weight.

Size is what's throwing me. Am I looking for only 18 x 8.5s? Or could I do a 18.9? I dont want to have to do any sort of fender rolling, or have to use spacers. Actually what are spacers? Also what is offset? Does any offset specs have anything to do with whether they fit or not?

Also the TPMS stuff doesnt bother me. I just want a lighter wheel, that I could put better tires on, and swap them out monthly for the autox. and swap back to stock afterwards. No other adjustments needed.

With all that, what am I looking for in the for sale seciton? I seem to be asking the same most likely dumb questions to the seller all the time. It would be better if someone would tell me based what I want to "look for these specs"...... and you'll be set.

 

Droppin' knowledge not bombs

Offset: The offset of a wheel is the distance from the mounting surface of the wheel to the true centerline of the rim. A positive offset means the mounting surface of the wheel is positioned in front of the true centerline of the rim / tire assembly. This in effect brings the tire in to the fender well more. Conversely, a negative offset means the mounting surface of the wheel is behind the true centerline of the rim / tire assembly. This will cause the tire to stick out away from the vehicle.





Useful website: www.1010tires.com

It has info on the wheels they sell there - full specs showing sizes and weights of the majority of the wheels they supply.

As far as which wheels are for you, it really depends on if you're just gonna track it or autox it for fun or seriously - because theres different divisions to consider at that point.

Hopefully this helps

 

Basically wheels just for autox for fun. I dont care about not being in a certain class. The autox I do is just a car club that goes out mainly for fun. Not really any classes. Hence the not too many requirements. I just want the wheels lighter and able to fit.

 

You said you wanted wheels which are the same size as stock, Which is 18x8.

Then you asked if you could get an 18x8.5 or 18x9...Well you could, but that is not the same size as stock...

Many different sizes of wheels will fit. Find a wheel, let us know the size, or do some searching in the "Will It Fit" thread because chances are, it has been asked.

 

Shoot I thought stock was 18 x 8.5. That helps.

 

Why not go for thicker meat while you're at it? More grip = more win.

I was thinking about these. A tid bit more thicker and lighter. Any disputes?

 

The Enkei RPF1 is one of the, if not the, most popular aftermarket rims for the '8. Reasonably low cost, low weight, excellent construction and good looks.

Wider can look better (eye of the beholder item) and in many regimes perform better (autox/track) but keep in mind that for the street stock 18x8 is optimal. In fact even for the track many go staggered to preserve the optimal steering response of 18x8.

Consider your typical driving when selecting tire profile as well. Around here I don't dare go lower than the stock 225x45's. The tires are an integral component of your suspension system. But if you're going purely for looks and/or you frequent very good (smooth) roads, then you have many options available.

 

+1 on buying the rpf1's. Fits your description

 

17x6 is the best`

 

The 18x8.5 rpf1 weighs 18.3lbs... which is much lighter than stock.

 

+1 rpf1 like mine. ^_^

 

As may be seen from Atilla's illustrations, the higher the positive offset number the more the wheels "tuck into" the wheel wells. Conversely the lower the positive offset the more they stick out of the wells (which is where potential rubbing requiring fender 'rolling' comes in if a lowered suspension).
Our stock rim offset is +50. Many folks go with +38 to +35 aftermarket to get a more flush to the exterior fender look.
btw: negative offsets are more for a "deep dish" wheel look relished by muscle car types.

 

Thanks guys, I've decided to go with the Enkeis. Is it pronouced "EN KEYS"? I know nothing about wheels. Now to read up about the suspension.
