Default HELP, need your advice

I live and Vancouver BC, and just drove to Winnipeg though the states. Some parts on the hwy is very bumpy and because of the extra weight from the STS system it made the car lower, and with 2 sets of golf clubs 2 bags and all isnt helping too. When i hit the bumps the rear right tire will rub the wide body quarter panel and i can smell rubber.

So what do I do?? I can’t drive back like this.

the easiest is to lighten the load. when you finish golfing, ship them home or to a neighbor or relative. softside luggage is lighter than even rollons and hardside, of course.

sounds like you're going to be doing some suspension stuff when you get home, like raising the car, different shocks, springs, wheels, etc. and maybe buying new tires, too.

if you come anywhere close to a good Corvette shop, you might call them in advance with your issues and ask if they can do anything if you made an appointment with them. if you come due south from winnipeg, you're a bit from DRM, a CF vendor, in Minnesota and Randy can probably help you out.

What kind of responses are you looking for? Your car is bottoming out because the suspension can't handle all of the weight you've added. The only apparent answer is to remove some of the weight or to avoid the roads that are exacerbating the problem.

Lighten the load is the obvious answer. Or you can drive it home that way and be prepared to buy some new tires, and whatever else. Also doesn't seem to be very safe. Maybe there's a better, smoother route.

I think I would do BOTH....lighten your load and seek smoother route even if it takes you a few hundred miles out of way....I'd rather drive farther on smooth road than a little less distance on a bad road. Does the STS add alot of weight?

and you know nothing is wrong with your Vette right?

Ship the clubs/bags back and take alternative routes.

Good luck!

Did you lower your car at all?

Which suspension do you have? If it's the F55 you can put it in sport mode and minimize the rubbing issues you're having.

Short of tweaking the ride height, I'm with the others in suggesting that you lighten the load and alter your route.

At least you have some great scenery to look at on the way home.

Good Luck.

The STS system dosnt add much weight. Its prob. because of bags and golf clubs.
Do you think bilstein shocks or new springs will solve this problem?

I have driven in Canada from Calagry toward Winnipeg (this was suppose to be the destination) on Canada Hwy 1, have been to Vancouver previously, and finally quit near Regina and headed south to North Dakota into the the "States". The roads were so patched from winter freezing and thawing that they tore my rear end up. A thousand miles or so later, a rear bushing on leaf spring fell out and the complete rear spring unit had to be replaced. Those roads will beat a stiff car to death! We even bottomed out on the seats going 55 MPH, horrible roads, same with North Dakota. The winter weather is really rough on the roads in the area.

Maybe it's just the way I'm looking at it, but if your avatar is the car in question, it looks to me like you have some very wide rear wheels. Granted, the weight you're carrying (I didn't think two sets of clubs weight enough to make the tires rub - are you sure you haven't got an electric golf cart stuffed back there as well?) is having some effect since, presumably, the tires don't rub when you're not carrying weight in the back.

That said, I've never checked to see if my car was heavily loaded if my stock wheels would cause the tires to rub?

I dunno, two sets of clubs just doesn't seem like that much weight. When we go on road trips, my wife packs like we're going on a 3-month African Safari and expects to attend several formal cocktail parties and receptions while on the trip. The cosmetics alone make we wonder if I shouldn't be required to have one of those signs like on commercial trucks to warn other motorists I'm carrying hazardous chemicals? Other than the inside rear-view mirror becoming as useful as a screen door on a submarine, I've had no problems with the tires rubbing with all that stuff in the back.

Have you considered raising your ride height? This is supposed to be easy to do (I haven't done it).

Here's an article that gives step-by-step pictures & instructions for lowering the ride height: http://www.vetteweb.com/tech/vemp_07.../photo_10.html

I bet any alignment shop in Winnipeg can make this kind of adjustment. Just tell 'em you want it raised, not lowered. And be sure they use jacking pucks to protect your rocker panels.

But this adjustment will affect your suspension alignment. So, keep a written record of the number of turns you raise each corner... then you can easily un-do the adjustment later.

And drive slower.

You bought wheels that don't fit your car. They should not make contact with the quarter. Buy wheels that fit or ship your stuff home.

Please note that I had similar problems with my C6, dealer commented that I had been on too many back roads, he wasn't saying nice things about Canada and North Dakota.

I have the same tire rub problem!! Completely stock 2009 LT1 C6 coupe and the right rear rubs while I am on some of the bumpy areas on interstate roads between Atlanta and Little Rock. It rubs enough that you can hear it and smell it. The lower part of the inner fender has rubber flakes on it. The tire has some scuffing. The right rear tire appears to stick out about 1/4" more than the left rear. All the suggestions about avoiding bumps and lightening loads don't apply here -- A stock automobile of any kind should not have any tires rubbing anywhere. Is there some sort of adjustment for this? Is this a warranty item? Thanks.

Yes, there is an adjustment; yes, it is a warranty item. Take it to the dealer if you don't feel comfortable doing the adjustment of ride height yourself.
