BTW I used my 00 ss as a DD and swore I would never get 315s on a DD again. If you hit a grove in the road, the car would steer where it wanted to. But I think that could have possibly been because the rim wasnt big enough for the tire.

 

tires twice a year. Dude, you must be beatin the hell out of em!

 

I installed my 17x11's last night. I Had around three hours in getting the rears to fit. I had to completly get rid of the bumpstops. There was no way they were going to work with them on there. The mounting point for the bumpstops was the part that was sticking out rubbing. I had to remove them and then cut all the mounting points and all that stuck out past the normal fender well away. Now i just have to be really careful not to bottom my suspesion out. I dont think i will have to worry about it to much though. I only travel flat roads with the car with me or one passenger.

 

Totally removing the bump stops is unwise, and unnecessary with 17x11 wheels in the proper offset.

 

yes, maybe unwise, but i had no other choice.

I have the zr1 wheels with 50mm offset. There was no other choice other than to remove it. I kept test fitting every so much that i removed and then it becamse obvious that it all had to go. I dont see how you say it is unnecessary when you wasnt the one putting the setup on my particular car, no offense. It wouldnt hurt to remove even more of the hump sticking that is on top of the bumpstop mounts but i left it the way it was.

 

Not so. Trimming of the bumpstops has been done many times on that offset. The bumpstops are needed to prevent more suspension travel than needed

 

I ordered a set of 18's for my camaro and I was thinking of going with 315's in the rear. Does anyone know of any issue? Thnaks New to the site.

 

I installed 17x11 +50mm ZR1s on my Camaro - a car with the same inner fender sheet metal, bump stops, axle, etc. I did have to grind quite a bit away from the bump stop and mount, but I was still left with a fully functional bump stop. Clearance at the back of the wheel is tight, but sufficient since there's very little lateral wheel movement in our cars.

If you found clearance to be more of an issue on one side than the other, you need an adjustable panhard rod to center the rear. Many/most guys with 17x11's have gone with an adjustable PHR for clearance issues or just aesthetics.

Bump stops are an important component - that's why they're there in the first place. You might never have a problem, or you might encounter a surprise pothole that sends one of your rear shocks into the interior of your car. I wouldn't be comfortable taking that chance.

 

Your right. I may encounter something risky. But that is the chance im going to take. In what i was viewing when installing the wheels/tires, It was going to be a certain thing of the sidewall/wheel coming in contact with the half ground bumpstop. The sidewalls on these tires are not very think and would easily be slit open. Right, i only paid $100 a piece for rear tires but I dont keep a spare and would rather not have that happening. I am taking the chance that an expecting pot hole with come up and **** the car up. That is just a chance i am taking. If i get to paranoid about it, i will order some universal bumpstops for $10 and fab up a new set. Easily done. But for now. I drive the car very little and carefully. So maybe ill be ok. If not, i post pics of the damage and a title of "This is what happens when people tell you something, but you didnt listen-!Bumpstops!"

 

You could put AirLift bags in the coils. 10-15lbs of pressure should keep it from bottoming out and not affect the ride.

 

Pics!!!

 

Pics of what? Wheels/tires? No bumpstops? Trashed body from contact with the axle?


About the air bags; I was wondering about this the other night when i was installing the wheels. I had a budy who ran them on his cobra but wasnt for sure if they would work for this or not?

 

You have to understand that not all f-bodys are built with in the same exact tolerances. When you put a 11" wide wheel on it fits very tight and on some cars little modification is needed while others (not being built to exactly the same specs) need every modification to operate smoothly. Im also one of the unluckys to have had such a car.
My bump stops rub on both sides and the only way to fix it is to remove them because if i grind on them any more they will just fall off. Im looking for an alternative before i remove them though. As far as i know i have 2 options; put in AirLift air bags or mount another kind of bump stop further inwards. I think the air bags would be easer but the relocated bump stops would be more reliable since you don't have to keep checking the air pressure. If anyone has already done one of these please let me know how it worked out.

 

Me too! Im going to crawl under there this weekend and take a peak at what i would need to do to mount so universal bumpstops from jegs. They run $10 or so. I figured i would have to fab up some mounts to weld onto the body. If it doesnt look like this is going to work, I guess i will go with the airbag theory. I may look into the bags first anyways, but dont know a whole lot about them.

 

I'm running 335s on my car and I was able to retain my bump stops. Hummmm.
