Default Suspension or Wheels

2000 Corvette Z51. 70,000 miles. Tires are worn out. So, the question is...

I don't mind the look of the thin spokes but would like to update the look and put larger wheels on the car BUT, I don't want to add heavy wheels to my car as I like the performance and how light the factory ones are. I also like the chrome 5 spoke look. Would love to do 19/19 sized wheels. The only ones I've found that are light enough and fit the look are the CCW SP500's. But even they are about a solid grand more than I can can really afford.

So, as I like performance and don't mind the look of the thin spokes, I've been throwing around the idea of just purchasing tires for the stock rims and using some of the extra money for upgrading the suspension with a Johnny Oconnell Stage 1 kit.

The reason for all of this? My wife has a Roush Mustang and although the Vette is quicker on a straight. Her car is FLAT in the corners and I would like something that corners as well if not better. Larger wheels mean less sidewall roll over, tighter steering response, etc, but better suspension would keep the car more planted and flatter. So I am a bit torn as to what I would enjoy more.

So your thoughts. Larger wheels or stock wheels and upgrade the suspension. I have about a $3000 budget in Canada (shipping costs are a killer!).

Best bang for the buck.
Also change the sway bar end links to metal, the 2000 is hard rubber.

And with the money you save on C6Z shocks and sways, you can pick up a set of used C5Z wheels and new wider, stickier tires that will finish the deal. Then you can sell the thin spokes and buy a C5Z ti exhaust. You might even save enough bucks for some headers and a tune.

I sold my CCWs---they were a royal PITA to keep clean and shiny.

Thanks for the replies guys!!! That is one of my biggest apprehensions on the CCW's. I like low maintenance stuff. That doesn't mean I don't like taking care of my stuff, I just don't want to be a slave to it. If the C5Z's were larger diameter, I would jump on them and for some reason, I've never been a huge fan of the look of those wheels. Don't know why. I have Borla's on the car right now otherwise Ti's would be on the list. Would love headers but that is a upgrade for a future time.

So far it seems the suspension is the weak link.

Check out the TSW Nurburgrings. Light weight and one of the best looking wheels on a C5 IMHO

What tires are you running now? I would suggest that your choice/type of tire is more important than wheel size insofar as your car's performance is concerned.

I have a 2003 Z51 6 spd. Vert. that I kept the thin spokes shod with 245/40/17 frt. and 285/35/18 rear Michelin PSS tires, C6 Z51 sway bars, Bilstien sport shocks, lowered on stock bolts that handles quite well. I too like the look and weight of the thin spokes .

Tires, shocks and any other suspension upgrades. A lower profile tire and wheel probably won't out corner your stock size. The tire design has more to do with that than profile. If your Vette isn't out cornering the Mustang with both cars in equal condition there is something wrong. I'm not a pro but I do have experience in Solo II with both cars and I will take the Vette any day.

Do the suspension upgrades and keep the stock wheels. You'll notice the difference and when funds allow, make the change to new wheels.

My suggestions: pick up a pair of thin spoke rear wheels (18X9.5) and then run 18 at all four corners. I did so with 275X35X18 in front and 295X35X18 in the rear. Then add your suspension upgrades (C6 Z51 sways, C6 Z06 shocks, and metal end links). Get a new alignment and chase that 'stang down in the corners and blow by her in the straights.

I upgraded to C6 Z51 sways with metal end links earlier this year and kept the F45 Selective Ride. The difference was night and day, I just didn't want to get rid of that feature.

You might be able to save a few $$ and check the C6 Parts F/S section for the Sways and shocks. Either C6 Z51 or C6 Z06... TSW's make nice, more affordable lightweight forged wheels. Either the Nurburgring's or Interlagos. Not sure if they have 5 spoke option though.

So far I am running stock sizes on at least 5 year old Kumho Ecsta-SPT Tires. I don't have any experience with other tires but they break away a lot quicker than I would expect, maybe just because they are old. I don't know the date stamped on the side of them.

An excellent choice but I can't do those wheels. A friend has a set already.

The Roush is lowered with 20" rims and around 45,000 less miles on the suspension and the Roush suspension is TIGHT. Tires are also a year old...but it IS heavier! I have frame protectors for my car and am looking to take maybe 3/4 to an inch out of the height to close up the gap in the fenders a bit.

Thanks VJ! I think you are pretty much summing up what I should do!

Hmmmm. Very interesting idea! I thought about it but not too much, however, this may become an option.

Thanks everyone for the replies!

Shocks and sways (Bilsteins/C6) should help on the street (since you're not racing) and a set of wheels will really update the look.

Both doable on your budget.

From a street performance perspective, I'd say it'll triple your costs and make no perceptable change . . .on the track - - a noticable difference.
