Rear C6 19x10's all around

Rear C6 19x10's all around I would like to do some 19" C6 wheels all around and can probably get the best deal with tires buying rear take offs from C6's. With their offset I believe to be 79mm as I have been searching, can I just run a 1.25" hubcentric spacer on all 4's and be good, or should I do a different size up front? Thanks in advance!

Been there, done that...I ran OEM C6 19x10's all the way around with 275/30/19 tires on my '98 Z28. I used 1.25" adapter/spacers on all 4 corners. I got tired of how rough the ride was on a 30 series tire and I'm now back on C5 Z06 18x9.5" rims all the way around.
Do a search with my username and I'm sure you'll find tons of pics of my old set-up.

thanks! I have 19s/20's on the vette so I'm used to the low-pros

If you're looking for some 285/35/19 take off tires from stock C6 vette's with approx half tread life, let me know. I bought 6 tires for my Foose speedster's, but they won't fit, so I've decided to sell everything. Wheels and tire. I'm asking $25 per tire plus shipping. PM me if interested.

Right now I have c6 wheels on my car. I don't mind the 18's in the front, but what are my options for putting 18's in the back? Seems like a stupid question, but will the front wheels fit on the back? Also, could the 19' wheels and tires be causing my wheel hop problem?

IMO, if you want to run C6 18" rims in the rear, then you're going to need to go with an aftermarket rim.

Test fit your front 18's on the rear and see what you think. When I tried it, I couldn't get the 18" C6 rims to clear the hub on the rear...it looks like I was going to have to ream the hole on the 18" rims a little to get them to fit. The bolt pattern of course is the same, but the rim wouldn't sit flush against the rotor due to the hub isse. I suppose you could run a spacer to fix it. The stock C6 front rim is only 18x8.5, so that also limits how wide of a rear tire you can put on.

Just brainstorming right now.

However, if you look into the General Tire Exclaim UHP tires, the prices for 19's aren't much more than 18's. I'm currently running the Exclaim UHP's in 18" sizes and I'm VERY happy with them!

As I mentioned earlier, to make the stock 19x10's on the rear have the same overall height as a stock F-Body wheel/tire combo, you'll need to run 275/30/19 or 285/30/19 tires and the ride with those tires is HORRIBLE! 30 series tires have very little sidewall. Also, the traction is bad with 30 series tires because you don't have any sidewall flex. I ran the 19's all the way around for less than a year and couldn't stand the ride or constant traction loss if I got on it, so I went down to 18's with a 35 series tire and I'm MUCH happier. The 19's also add more weight.

The lesson I learned was that anything over an 18" rims with our cars is going to cause a lot of compromises as far as peformance and ride is concerned. If the look is more important to you than ride and performance, then go with tires bigger than 18", but if looks and performance are important than don't go bigger than 18's.

The only solution I know of would be to go ahead and run the stock 'vette sized tires (285/35/19 I believe). However, they're over an inch taller and your ride may improve, but your acceleration will suffer. Going with a bigger tire is the same as going with a numerically smaller gear, so you would need to also have the computer programmed for the bigger tire to keep your speedometer accurate.

have rode in a 2000 formula and a 2001 WS6 and I feel like my car is significantly slower. Engine uses no oil between changes, doesn't knock, rattle or any of that crap. Maybe its just in my head. lol

According to the tire size calculator that I use, if your speedo is still calibrated to the stock tire size, then you should be 3 MPH off at 65 MPH on 285/35/19's...your ride probably isn't near as bad as it would be with a 30 series tire...I'm actually surprised you're not happy with the ride on 285/35/19's.

I can't really say that a 245/50/16 tire is going to be .x quicker to 60 MPH or that a 19" tire is going to take away x amout of power on the dyno though. I would love to know those types of numbers too, but that would take someone doing back to back testing on a dyno, etc.

On 4th Gen. F-Bodies, you want to keep the overall diameter of the wheel around 25.6" If you go a lot over or under that, then you'll need to have your speedo recalibrated. It's the weight of the wheel/tire combo that you need to worry about. A 245/50/16 tire and a 285/30/19 tire will both have the same 25.6" diameter, but obviously, the weight of the 19" rim is going to be heavier than the 16" rim. Also, the bigger the rim, the smaller the sidewall you're going to have on the tire too. Both of those issues will affect acceleration. You can pay $4K - $6K for a set of large lightweight rims if your want to go bigger, and not have any problems as far as the weight is concerned. But just as mentioned before, the larger the rim, the less sidewall the tire is going to have which also affects traction and ride.
