Did you test fit the rims yet?

blown81bu

rims cam out at 23lbs
with tires 42 lbs

my stock front wheels are 58

robz

Thanks.

Here is some general info I gathered:

(not sure if any of these rims will clear our brakes but they may be worth a try if you can borrow a set or get used cheap.)

Stingray rims 18x8.5 ~24lbs.
C6Zo6 rims 18x9.5 ~21lbs
c5 base rims 18x9.5 ~20lbs
c5Z05 rims 18x10.5 ~

I will test fit the c6Z front wheel on the rear of my car.
I'm told that a c6GS rim will fit the rear of a c7GS/Zo6 (non-carbon) from a vendor

Forgestars are light and much cheaper than most (f14) as Jesse can attest to. Need to make sure they clear front and back on the car while moving, turning, stopping, etc.

Forgestar 18x5 ~18+lbs depending on finish
Forgestar 18x12 ~26lbs
You can estimate weight for sizes 9-11
Seems like vendors willing to make deals as well esp. with multiple orders

Other forged wheel companies are going to be big $ and all have to be test fit and likely custom made.

The M&H tire is a bias ply and 28" diameter. Good for a 4-5" rim. One concern is that it throws off the rake somewhat and it may possible run the fender especially on hard braking.
The M/T sportsman radial tire seems like a better fit to the 18x5 inch rim all around but its a bit bulky and weighs about 18lbs. The tire should fit car no problem if the rim works and as Jesse noted you are saving ~20lbs per corner up front.
~57lbs(stock) -~37lbs = ~20lbs

We are talking street cars here and looking for performance with compromises. 18" front runners work but look goofy to me.
No doubt an 18" can hook and perform but I'm concluding that if anyone could get a 17" drag pack to work it would be much better for tire selection, looks, performance, etc..
Not sure I even want to drag race this car but I'm committed to helping others find the right combo for their setups.

The racestars are another option but have fixed sizes. You can see them on Norcals car and they seem to fit but I'd confirm with him.

To my knowledge, nothing in 17" works front or back without conversion kits.

Jake at Vibe Motorsports has the hookup.

A C7 Z06 was found local to Forgestar for a test fit of the 18's.

I'm still under the weather here people with a cold and sore throat, not going out into a cold garage until I'm better. Give me a few days.

I think those M/T Sportsman SR's will be the go to front tire.

Love that narrowed stock front rim!

Those 17's that Forgestar sent me might fit a Stingray with the smaller brake calipers.

I'm sure Jake could send them out again for a test fit.
They were 5X17 and 11X17.

I don't plan to run mine except on days I know I'm going to the track.

Mike Jesse

We have another forum member that ordered the complete set front/back in 18's. Maybe he will see this and chime in. Going on a GS I believe.

I've got a rear setup for the Stingray.
Racestar Darkstar 10.5X18 ET 75 mounted on 285/40R18 M/T SS Drag Radials.
9 passes on them.
Local sale only, too costly to ship.

My front hub adapter kit is the lightest option, uses any popular 'billet' 1pc 17x4.5x2bs front wheel from weld, rc comp, billet specialties to direct fit onto a c6z or c7z. No extra set of lug nuts, or changing studs, or caliper grinding needed. This takes 52# off the front compared to stock c7z (give or take based on wheel and tire combo chosen)

i have also made similar kits for narrow body

Carlyle Racing (AtomicFusion vendor screen name here) also sells a spindle kit allowing popular 17" weld or similar rear wheels to direct mount to C7 and 7Z (no lower control arms, for stock steel rear rotors and calipers) here for example:

I have not been on the track now in almost 2 yrs from breaking down the c5. But the best for the drag tire for the track was the non dot 275x50x15

robert miller

David set up looks bad *** man. Robert

Mike Jesse

It's fall at Dave's house. Those money trees are dropping big time.

I like it, but it's outta my budget.

robz

Yeah.
You know where I stand, brutha.

7100 rpms on an 8.5.

robert miller

Rob you are so full of it. If we had your money . Robert

FYREANT

I am considering a 17 inch conversion kit from Carlyle actually. It's an acceptable compromise to a 15 inch conversion and I can get matching wheels this way too since I will run them all the time on the street and strip. Matching wheel design is important for me.

After H/C, this is my next major spend. Of all the options, definitely loving the Welds.

robert miller

If you are doing it for a set up street & track then yes for sure. But again ANT when you go to the track mark your tire to the rim. See how much the tire moves from the mark you have made on the rim. I know in the 900 plus rwhp it moves a good little amount that is why when I did the RHS 427 F1X set up & 1270 plus rwhp. I had to do the weld 15 bead lock set up. But I never had a 17 inch only 18 to 15 one for the street the other track. You can always use the screws in the 17 if it moves a lot on you.

123sugey

Yup... and I still forgot to mention getting the job done

robz

I'm with you buddy.
At this stage I'm not willing to compromise any streetability if I decide to run at the track.

robz

That's understood.

I'm going to order small tires as long as those c6z fronts fit and take a few passes just to test my theory.
It's going to suck with the stock clutch but I'm determined to prove to myself they are the best option for my setup.
I think it's an even better option for the auto guys aren't making crazy powah.
Back in the day we put an IRS street vette in the 8's on a baby drag radial(255) that wasn't supposed to hook.

FYREANT

Personally I would prefer the 18" setup as it would be more cost effective and more visually aesthetic IMO so I am still looking forward to your offering!
