I am wanting to lower my car when I get my new shocks put on but I am thinking I am going to have a problem. I put on a set of 17x9.5 zr1 rims and used the adapters from skulte.com that we are suppose to use to adapt these wheels to our cars and the tire size is 275/40/17 but it looks like the tires all the way out to the outer edge of the fender so if I lowered it all the way down, which I am not going to just giving that as a reference, the edge of the fender well would be sitting on the tire. The tires don't fit all the way under the fenders. There is about 2.5 inches to the tire in the back and about 3.5 inches in the front. Will I have to roll the fenders a bit so the tires won't rub on the fenders or should I be okay with a 1 inch drop all the way around. Here are a couple pics of how the back tires sit. Hopefully this helps and if anyone can help me out, I would greatly appreciate it. I am hoping to do this in the spring.





Thanks for looking.

 

You have the wrong adapter size's the 17x9.5's should fit well
under the wheel wells.

I have 17x11's on the rear of mine and they don't stick out that much.

I would try smaller adapters, what size adapters are you using?

 

They are the 2 inch adapters that I was told by eveyrone I talked to and also from the people at skulte.com. I told them what can I had and what wheels I was putting on with the offset and backspacing of the wheels and I was told the 2 inch adapters was what I needed for the wheels to fit. What size adapters are you using?

 

eibach 1" lowering on my ZR1'S

 

When I had my SLP ZR1 17x9.5 I was runing a 2.0" in front
and a 1.5" on the back.

 

Check this post out, there is info on my 17x11 install.
I
just checked it and it appears that the site thats hosting my pics is down so you may check back at this post later to see pics.

Check with ES87iroc he has my old ZR1's and adapters.

 

Yeppirs, works great on my car with the 1.5" adapters. I have 285/40/17's and they fit great with no issues.

 

I have the 275/40/17's so I should have gone with the 1.5" adapters instead of the 2"adapters all they way around or just in the back? The front seems to sit out just a bit as well.

 

I have 2" in the front as well, which smaller adapters might be a better idea, but I don't know for sure.

 

i have 17 ZR1's 275 40's on all 4, and sportline springs... before i switched to a 4th gen rear, i used 1.75 spacers. and they were awesome. in fact i still have the spacers in the garage.

if you have the 2" ones and are not satisfied, have them milled. taking 1/4 inch off is not going to hurt it.

 

I have 2" adapters and am planning a brake upgrade that will add .300 to eack side. I called Andris Skulte who made my adapters to see if he would take .25 off and he said it would not be safe.

 

taking a 1/4 inch off the adapter is not safe?? ahahha OK more like he wants you to order another set.. having 1/4" lathed off is NOT going to hurt, take it off the front not the back.

infact there are 2-4 people on here(i cant remember their names) but they did this, 1 person took 1/8 off..

but is he saying its not safe because of the brake upgrade? or just taking some off period?

 

I agree with Andris. These things are not solid spacers. The holes that the studs are seated in and the holes that the stock wheel studs slide through have a specific depth to them and machining down the spacer will compromise that depth. Either the thickness of the portion of the spacer that the stock stud and lug hold onto or the portion that the outer wheel stud resides in will be thinner (aka not as rigid, aka not as safe, aka not a good idea).

IMO anyways......

 

Agreed. Any material removed from either the front or the back of these (Skulte) adapters will definatly weaken the design. There is a critical thickness you need between either the studs knurl and the wheel (front) or the lugs and the rotor hub (back). Taking material from either side will definately reduce these critical dimensions.

 

Hey ES87Iroc: I saw in your post that you have 285/40/17 on that thing in the rear. Did you have to modify your inner fender wells or roll the fenders to get them to fit? Also, are you using a lowering spring, and if so which one? Thanks, Paul Moore

 

Actually, they are 285/40/17 in the front and rear. The rears are a perfect fit, the fronts I had to do a little clearancing work, nothing complex though I did it with a dremel.

 

Hmm, interesting. I planned on running 295/35/17's out back and 275/40/17's up front but if the 285 will fit......
You are using a 9.5 inch rim up front, right? What did you have to do with the dremel exactly, if you don't mind me asking.
