I sold my stock posi axle and now have the cash to buy my lowering springs. I am going with the Sportlines b/c i really want the car on the ground. I am going to be running a 295/35/18 rear tire on a Speedline Z06 wheel and wanted to make sure this combo wouldn't bring me any surprises. I already have plans to roll the fenders and i'm prepared to "massage" the inside of the fender wells to get the clearance i need. Just wanted to see if anyone out there is running the same combo. I searched, but didn't come up with anything that answered my questions 100%.
Thanks....

 

it should not be a problem plenty of people running 315 with the proper backspacing. i run 305/30/19 with a 2" spacer and only had massaged the inner fender. but i do have umi lca's i remember the stock lca's were pretty close to rubbing.

 

Thanks godreject...
I'm planning on upgrading the LCA's and panhard bar as well, so it sounds like i should be fine with the 295 width. How do you like those UMI's? They seem like they're pretty well built. I would love to go with Spohn but some of their stuff is so expensive. Guess i'll see what happens as the car comes back together.
Gonna order my springs so i can get that 4th gen rear under the IROC and i can replace the rest of the components fairly easy from there.

 

umi's quality has been great so far, i really wish i would have bought the adjustable pand har bar though, specially if you plan on lowering the car my rear is slightly off center but not really noticible. umi has 15% off sales every now and then like this past weekend for their veterans day sale, im sure they will have another come thanks giving or xmas, thats why i liek to shop through them, you can save yourself some money if you buy a few things, or you can always buy a used set plus tubular lca's look good lol
