What size wheel spacers can I run with out have to get extended lugs?
I was thinking 8mm to 10mm?

 

on the stock wheel studs, i wouldn't risk anything beyond a 5mm spacer just for safety reasons. as easy as they are to cross thread they're relatively weak and putting more stress on the ends of them can't be a good idea; i've always been told that you want at least 7 turns on the wheel nut when tightening your wheels down.

 

Even 6mm is pushing it. It is best to put on the longer studs with spacers for the sake of safety. I am running 15mm H&R DRS in the back with extended studs, and they would not have worked AT ALL with the stock studs. Car looks 1000 times better with the rear tires pushed out from under the car BTW....

 

get the kic's 15mm that comes with its own studs build-in.

you dont need to dissassemble the drums or anything. i use it on my G35C.

 

pics?? are you still on the sport wheels? i've always been interested in this but never had the balls to try it myself.

 

Putting the 15mm spacer would make the offset +40 charlie so it would help a ton. (if he's using the stock wheels)

As said above 5mm is the largest that I would use with out running the extended studs, but some spacers (as posted above) come with studs already built in.

 

If you run a search for a thread i started called "It works!...I knew it would" you'll see the whole story from end to end with pics. The car looks much better w/spacers in the back IMHO. The rear studs are actually pretty easy to get out (of course i have a 12 ton shop press go figure) but the fronts are such a PITA that Ray figured out a way to remove them without removing the hub. Unfortunately it involves using a right angle grinder on the spindle, which was a little too adventuresome for me....

would spacers in the rear be beneficial to the car's handling in anyway?

 

Ever so slightly wider track in the rear can't hurt! I don't really feel the need for a RSB as the car already has more grip than i have nerve.

 

Yes and no . . .

A wider track lowers the center of gravity. A lower COG reduces weight transfer. Less weight transfer increases grip (to a point). But on a car that already understeers, a grip increase only on the rear end isn't going to be of much practical use. In fact, without other upgrades or adjustments it'll just exacerbate the car's less desirable handling traits.

That said, it also depends on how you define "handling".

 

that answered my question, thanks

 

That's right, pushing out the rear wheels has the similar effect as increasing torsion rate on the front swaybar. If you are going to push out the rear, push out the front as well.

If you want more over steer bias you want to pushout the front and leave the rear as is.

Another thing to note about the Kics is that you don't need any special tools. Just place on the hub, tighten down the special low profile lugs (kit comes with adapter), place your stock wheel, tighten down wheels using your stock lugs.
