I have a 06 g35 coupe and I'm looking to buy tein s techs, camber kit front and rear and run 20x9 front and 20x11 rears with a +13 offset. I will obviously be rolling my fenders but with the setup will I have to run camber still so that I don't rub? I drive about 100 miles a day so tire wear is kind of a concern. The tires I was looking at are 245's up front and 255's in the rear 35 series

 

With the S-techs you should be alright with minimal camber. You may tuck a little bit of tire, but the roll will probably give you enough clearance to be just fine. If I had to guess I would say probably around -2/-2.5 degrees at most which really isn't much at all. It's also possible to slightly flare the fenders with the fender roller for a little more clearance if you need it later on.

You can run a couple degrees of camber and not experience any crazy tire wear if your TOE is in spec. That's the most important part of the alignment where tire wear is concerned*. Also I'd recommend going with a non-summer/high performance tire if you've got a long commute. You just won't get any life out of them driving 2k miles a month and will have to flip a summer tire much more often to even out the wear.

*Explanation: Camber will cause uneven wear if part of the tire is in the air, but it won't cause excessive / accelerated wear if the toe is in spec. If toe is not in spec, even with 0 camber, you'll destroy tires.

 

If it helps I ran a 20x9.5+5 / 10.5+5 which is roughly close enough and never had issues after I got my alignment straightened out. 20s with springs is still going to give you enough ground clearance and a decent ride that you ought to be ok. I want to say Continental has decent grip tires with good mileage on them but I can't remember for sure.

 

Thanks for the replies. That helps a lot. So should I buy the adjustable toe arms too or can they be adjusted enough with the stock ones?

 

Always better to buy the adjustable arms front and rear, but the majority of guys on springs only seem to do the rear. I prefer having both, personally, but plan on the rear for sure and see how the alignment works out to determine whether or not you think you need the front also.

 

Im concerned about being too high with 20s. I have G S-techs, no aero. Looking at getting at least a front lip first. If ur getting G s-techs ur gonna end up with 1.5-2 deg. of camber. up front. Thats confirmed by me and another member elsewhere.

 

I shoulda been more specific. I'm getting 350z s techs
