Sounds about right ^

 

These are my specs. Lowered on Eibach Sportline.
18x9.5 +15 18x10.5 +15

255/40/18
275/40/18
Rolled rear fenders. The Square set up is also an option 18x10.5 +15 All around
Here's a pic

 

Many other tire options too
265/35 front and 285/35 rear
275/35 front and 285/35 rear

10.5 +15 is really not that great of an option, around -3 front camber is needed. Good for track, not street.

 

So what would be a good offset for the streets on the front end of the car? 15+ for the rear is fine right?

 

can I run oem alignment specs in the front w this set up?

 

9.5 +15, is what you want. and you may need a slight amount more front camber than OEM spec. OEM specs suck anyhow -0.3 to -1.1 i believe but it shoud be -0.6 to -1.5 IMO


Pull up and offset calc < Google the bold, and you can see the difference between 10.5 +15 and 9.5 +15

 

That much camber wudnt ruin my tires right? I really dnt have much clue about this..I wud like to run 245 in front 275 in the rear...

 

If you do a lot of corner turning it will mmake you tires last longer, if you have nothing but straight roads like us who daily drive in Vegas , it will reduce your tire life by a few thousand miles. No big deal.

Ive was runnning around -2 on the street for a few years and still got around 30k out of my street fronts, then for the year before my car became a dedicated play toy i was running -2.8 up front and still got over 25k out of them.

Camber hurts a little, inproper toe will screw up the tires in a quickness.

 

haha yea dude i live in long island NY i dont see straight road unless i get on a highway......ok so so far this is what ill do 18x9.5f 15+offset and 18x10.5r 15+offset rear, 245 tires in front and 275 tires in the rear w a slight fender roll? any other info u guys might suggest?

 

255/40 front

 

Wudnt this be too much ratotional mass on the wheels\tires? Nd possible affect mpg? And performance?

 

Then keep the 245 up front and get a 265/40 for the rear.

No point of increasing the width stagger and making it understeer worse than stock.

 

Best? DEPENDS.

I only have about -2.5, run a +15 10.5" (in the front) and use a 315. I do, however, run a lot more spring and bar than probably anyone on this forum. That said, it only rubs on occasion (did cut a tire down when the car got airborne).

A 275 should fit no problem with low -2 (or more camber) on the front I would think.

Didn't even rub on high grip concrete (and the car was rolly as s__t)

 

18x9.5 +15 up front with 235/35/18
18x10.5 +25 rears with 285/40/18

No rubbing at all. Just a lil camber /w fenders rolled.
Im waiting on my 255/40/18's for up front

 

looks nice! . is that gunmetal color or sbc?

 

what suspension you on Midnight Slide?

 

so much win in this thread. I'm gonna start saving up for a set of RPF1's now and have them professionally custom painted.
