I'm going to buy a set of tires for track use only (probably Michelin PS2 Cups) on my '05 Z-51 (Bilsteins, Z06 bars, track pads, SS lines, cooling ducts etc.)

Wondering how many of you have mounted your track tires on (heavier) repro wheels, like Z06 Motorsports, Ace, etc.

I know "lighter is better", but the budget won't handle $1700 for tires and another $2500 for light wheels.

Is the weight difference really noticeable ???

Would appreciate any input, THANKS

I'm using OE Concepts ZR1 17x11" replicas for my track wheels. They were cheap ($470 brand new with tax), but they definitely aren't light.

Unless you're really, really fast, you probably won't notice difference in weight. I'd just make sure you buy something that's not going to break. JMHO.

I did the reverse, use chrome Z06 repros for street driving and the OEM's for the track.

That's why I ordered painted wheels because I knew I was getting chrome repros for the street.

I have OE concepts black motorsports with Toyo RA 1's for the track.
I got confirmation from the manufacutrer that these wheels would hold up at the track. They ran additional tests to verify it for me. It took a few weeks to get the results.

I am an intermediate HPDE driver. Can't tell the difference in weight.
I went from OEM Z06 wheels and GY F1 Supercar tires to the above setup.
Handling and grip are much better now. I know it's not an apples to apples comparison but it works fine for me.

with all the above posts. I'm using chrome Z06 repros from Corvette Garage, with Toyo RA-1 race tires. I paid $600 for all four including shipping. Never had a single problem.

My opinion is, "Why spend a fortune on wheels for the track, because no one cares how they look, and any decent wheel can take the abuse? Light-weight wheels are for the upper echelons, not for us weekend hobbyists."

I picked-up a set of used OEM's for my Hoosiers and it was a good choice. I was using heavy after-market rims and I never noticed a difference on the track, but there is a BIG difference in hauling them around, on and off the tire rack, and mounting/dismounting.

I have, and use, both OEM and aftermarket. The weight difference is significant - but not relevant to a weekend track warrior....

If you are running for the podium in Time Trail - go for the light wheels....

Most, if not all, of your answers have come from C5 guys. Remember that the C6 uses different backspacing and offsets than the C5. If you want wheels that fit "properly" you're somewhat confined in your choices.

That said, MattW_VA uses C5Z rear wheels all the way around and reports very little rubbing on his C6... much less with the T1 suspension in place. You should be able to find those for about the same price as the heavy repros...

Yes, I am looking for info on C6 repro wheels for the track use.

Yes, I know C5 & C6 have different backspace, but I wasn't aware that there were "confined choises" for repro C6 wheels, they appear to be quite plentiful ???

Who out there has used REPRO (Motorsports, etc) wheels on a C6 on the track ???

THANKS

gkmccready

Look more closely. You'll find that most of the "C6 Repro" wheels are actually C6 repros in C5 backspacing/offset. I *think* TireRack has C6 repros for C6s, but most others are C6 repros for C5s...

You're probably looking to run an 18in rear to improve tire choices, too, right?

mwvettec5

I don't know, I think Bob at House of Wheels in FL has a number of choices in repro wheels for a C6 - like Comp Grey Z06 in 18x9.5 and 19x11.

That seems ot be conventional wisdom, but in the Michelin Ps2 Cups there's no better choice in 18" rear than in 19" ???

gkmccready

Toyo RA1s 275/35r18 + 305/35r18 on 18x10+18x11... this is the recommended street/track setup from John@CCW.

Or 18x10.5 C5Z wheels with 305s everywhere?

Or ... why PS2s? Why pay more for 19s?

mwvettec5

Great setup, likely better than PS2 Cups, but I don't have the $$$ for CCWs, where can a guy buy "repro" (or less expensive) 18x11 wheels ???

Aren't C5 Z wheels the wrong offset for a stock bodied C6 ???

Toyo does make an 305x18 RA1 ???

Curious mind(s) want to know .............................

THANKS

Good question; I bet the ones I recall seeing were the C5 ones. :-(

What are you looking at with running repros and Michelin Sport Cups? I don't see much in the sizes for a C6 non-Z. I don't see much in the Pilot Sport PS2s, either.

Yup. But they work with minor rubbing from what folks have said.

Yup! http://www.toyo.com/docs/tires/produ...category=sport

I am using Factory Reproductions on my C6Z. 12's on the back and 10.5's on the front. Very, very little rubbing on the front. We have put them in my buddy's C6Z51 and they seem to work. The overall quality is very good.

They are heavier than stock wheels. But they are reasonable $$ and at my level, the weight isn't a consideration.

I dealt with Bob at the House of wheels. Very knowledgeable.

I currently have PS2s on my Z-51 -

275 x 18 on 18x9.5 front

305 x 19 on 19 x 11 rear.

It looks like Cups are available in the same sizes. The rears are pretty expensive but $300 more for a set of (4) tires is not too much to get the right diameter difference and to avoid rubbing.

But I will do some checking on the Toyo's and C5 Z wheels.


THANKS

mwvettec5

You put Z06 size wheels on your friend's Z-51 ???

What tires sizes and how much do they rub or stick out of the fenders ???

Curious .......................

Where'd you get those wheels? Stock are 18x8.5 and 19x10?

www.tirerack.com doesn't list a 275/35r18 for the cups -- I see a 285/30r18, though, and I only see a 305/30r19.

285/30r18 is an inch shorter than the stock 245/40r18. And 305/30r19 is about 7/10ths of an inch shorter than the stock 285/35r19. At those sizes your 6% larger in the rear. Stock Z51 is 4.4%, and Z06 is 4.3%. The Toyo setup suggested by John@CCW is 3.2%.

Oh, PS2s have a 275/35r18, and a 305/30r19, which is a 2.4% difference. If those are working for you, that's a great data point, thanks!

$300/set of tires doesn't take many sets to make up for getting those CCWs. :-)
