I did some searches, so no one jump on me now

I was to lower my car with the red eibach ssprings, which are 1.5" to 2" I believe. I was also about to buy some chrome oem z06 wheels, 17x9.5" in the front and 18x10.5" in the rear as well as the factory tires that come with 'em. I'm just concerned about the tires rubbing. Has anyone done this ? and should I be concerned with the tires being too big with the car lowerd? If so, my second choice was the Y2K wheels and I would get 275s in the rear and what? 245, 265 in the front?. I figured that would be ok.

Thanks in advance.

with 18x10's you may need to do some work like rolling the lips of the fender. only on the back thoe. i think it's the same with 18x10.5's...???

i'd do 18's all around, if i were you.

 

Well first you'll need spacers. 17x9.5 should fit the front fine, but 18x10.5 with the sportlines... I dunno. Like tim said, you'll need to roll the fender lip, and probably massage the inner fender with a hammer to get it to fit without any problems.

 

I have four 18x9.5" Z06 rims on my car dropped 2" all around. Each rim has a 10.7" wide tire on it, so if you ran a 275 on the rear I'm certain it will fit. However There's sufficient room for a bit more meat under there.

I don't know if this pic helps but it's the only one I really have of the rear tires. At least it shows how the wide rims sit with the 2" drop;

 

I never get sick of looking at your car!! Its the wallpaper on my desktop at the shop!!:hail:

 

Thanks, bro! :rockon:

 

yes, the old persuader, forgot that part.

 

Well, I am not doing anything major to my '91 so I am still going to contine to lower it. I'll probably go with the chrome Y2K's though. 18x9.5 all around. Let me get y'alls opinions though, my car is black, so chrome y2k's or chrome z06's?

By the way tpiroc, where did you find z06 wheels in the 18x9.5" size?

Thanks.

Haha, yeah... I forget where I heard the quote but someone once said "My favorite tool is the sledge hammer... because everything either has a problem going on or coming off."

 

9.5 is pushing it in the front but possible. 10.5 isn't possible in the rear without some major work on the inner fender. i'd stick to the 9.5's in the rear if your dropping that much. 10.5's will work but either way your car will look like this.

8 front and 10 rear is really the best widths on the car unless your closer to stock ride height or as most consider it the worn spring ride height which case 9.5s in the front and 10.5's in the rear are ok. this also depends on how you want the tires to sit on the car.

if your going to go with vette rims i'd strongly suggest no wider then the 9.5's. 8.5's front and 9.5 rear would be better. that is unless you don't mind your wheels outside like in this pic. these are 18's 9.5 front and 10.5 rear brought in as far as possible without inner fender work. wasn't bad but i couldn't lower the car more then a 1.5 prokit stance and if i had two people or more weight in the car the rears would rub under hard acceleration and the fronts would rub under hard cornering. but, if you baby the car and don't drive hard you shouldn't have any issues given your springs and strut/shocks are in good shape.

 

I would like to put 275's up front and I don't think I can do that with a 8.5" wheel up front. 18x9.5's all around would look really good too, as I can see from the pictures. What size adapters are y'all running? I have a 4th gen rear end so I only need adapters for the fronts.

I found some y2k wheels 18x9.5" with a 68+ offset...So would 2" adapters work? Sorry for all the questions, I tried searching myself, but didn't it didn't answer any of my questions. Plus I'm kind of in a hurry because I'm getting my car back this weekend and I wanted to order the wheels in the next two days.

I almost forgot to ask, anyone know the offset of oem y2k wheels?
Thanks again.

no you would need larger then 2".

i have a pair of skulte adapters that i used for my 9.5's up front with that offset but you would still need to purchase two more. 9.5 is the correct width for the 275 so you should definately go with that. i didn't like how the wheels stick outside of the car but everyones different. they do fit and they don't look all that bad so give it a try if you like.

 

I wish they made a 18x8 Chrome Z06 replica. That would be ideal.

 

well the backs aren't the problem but an 8" replica for the front would have been great indeed. have one custom made.

 

I'm finally getting my OEM Z06 wheels next week. I'm planning to get 2.25" spacers all around, but I haven't ordered them yet. Car is not dropped yet either, but I will be installing a set of Eibach Sportlines the week after next. Before I roll the lip or bust out the BFH (problem solva! haha), I'll see how close the 10.5" rears (295 tires) are with a Sportline drop. From my previous experiences with the Sportline rear stance, I dont think I'll need to roll the lip. But we'll see what happens, and I'll try to take some pics. This is all going on an 89 IROC BTW. Lates!

 

is there a problem with the fender for EVERY 10-11 wheel or is it only on wheels that require the skulte adapters? im wanting to run a 17x10 custom Boyd Coddington wheel in the back. ive also looked about a set of Drop zones or sportlines so that must be considered also.

 

For the inner fender, it would depend on the backspacing of the wheels. So its not something that is related to running adapters, but more something related to the final backspacing of the wheels (with adapters or without). Sorry I dont have any specs for 10-11" wheels that will guarantee work, but I do know a 9.5" wide rear with 275 tire and 5.5" backspacing fits fine without inner fender modifications. Running these Z06 wheels will be the first time I'm going wider than that (they are 10.5" rear with 295's) so I'll know more about it after doing the mod. For the fender lip, it all depends on the stance of the car. If the car is lowered and the springs are soft enough to allow the tops of the tires to pass the fender line while dampening, then you might have a problem. A stock height car might not have any issues, while a modified lowered car can have alot. I've run the Sportline springs with 9.5" wide wheels with 275's on the rear and had no issues at all. In fact there was quite a bit of fender gap and space between the wheel/tire and the body of the car (both inside fender and outer fender). But the fronts were a different story ... IMO the Sportlines spring rate is too soft for the ammount of drop (an effect of progressive rate springs). This causes major possibilities of rubbing issues in the front with oversized wheels/tires. I'm guessing I'll have more issues with the fronts of my Z06 wheels and Sportline springs than the rear, but we'll see what happens!

 

I have to ditto an earlier comment on Tpiroc's car.

To me, it is the finest looking 3rd gen I've seen.

Great job man!

i have the Skulte 2" adapters and OEM Zo6 wheels and all fits well. I'm running 275\40\17 in the front and the only thing I had to do was to grind the outer tie-rod end down a little so it wouldn't scrape the wheel. As for the back you need at least a 295 cause anything smaller doesnt have much of a sidewall and is kind of rounded. I'm running a 40 but you could probably go to a 45 and still have clearance.
