Hey guys,
I am putting 20" STR 607's on my 2011 g37x coupe. I want to put eibach lowering springs on it with 15mm rear spacers and 20mm front spacers. Do I need to get a front camber kit? rear camber kit? or just an alignment? there are so many different views on this out there so I needed some help. Also, is 1.9" drop in the front going to rub?

 

get the front and rear camber kit just to be safe and so your not burning through tires getting uneven wear

 

yea but some people were saying the rear was fine and no need for a camber kit. So i just didnt know.

 

You can get your Toe within spec without a camber kit, but you'll still be burning through tires with excessive camber from the drop.

 

I had to get the rear camber kit when I lowered mine on Eibach lowering springs. The shop that did my alignment said that it would have been alot easier to install the camber and toe bolt kit while swapping out the springs.

 

Most people tend to like to get camber/toe bolts to do it all at once. I am lowered on h&r and it's even lower than eibach's and I choose not to run camber kits. As long as toe is set right, I'm fine with a little bit of extra camber. Most people mistake and think camber cause "excessive wear" to the tires when its actually toe that will cause severe wear. While it may cause some inner wear, it's not as bad as people make it seem..plus you can always flip them.

Why run spacers with aftermarket wheels? Get the correct offset so you can avoid spacers. I'd opt not to run camber kit since eibach is one of the mild drop.

 

ok so dont run cambers but how do i get my toe set right? and if im getting the after market rims, what would be the correct offset? I am totally lost on the offset subject.

 

Depends on the width of the wheel, the offset is the amount in mm from the centerline of the wheel, a zero offset would be mounted at the centerline, a positive offset is mounted closer to the outside of the wheel (which pulls the wheel into the fender), a negative offset is mounted closer to the inside of the wheel. Offsets in teh +20 to +45 range are pretty typical and real aggressive setups with the wheels pushes out beyond the fender running big camber and stretched tires & fender pulls can run zero or even negative offset.
Pic a style of wheel w/ the widths you want and we can help w/ offset.
BTW, I'd get the camber kits if you plan on a long term lowered G, the tire wear long term will pay for the $500 camber set, but that's just my 2c's.

 

my friend just got the same rims and same set up as you with the pro kit drop as well. His car is a xs and all he needed was a alignment.

 

Ok thanks. I think im gonna go with STR 607 20x9 & 20x10.5 rims with 245-35-20 & 285-30-20 Accelera Tires. I want the tires to be flush with the wheel well. what would the offset need to be to do that? and does that mean I dont need spacers?

 

So his alignment was back to factory alignment? You sure he wont need a camber kit because of the wear on the tires?

 

With a moderate Eibach drop offsets like +35 F +45 Rear should be

 

I just lowered my car today with eibach pro kit and the Spc camber kit. If your going to lower your G, I say do it right

 

Don't know if this helps but my Coupe is currently on Eibach PK and I'm runninng a 245/275 F-9.5+32 & R-10.5+37 front could use a 5mm spacer but my rears r pretty flush.. And I don't have camber kits.. All I needed was a GOOD alignment from a reputable Performance Shop that knows what the heck they r doing!
