ok which wheel adapter?
ok which wheel adapter? just want to get that flushed to the fender look ok, so I have OE wheels C7 Z06 wheels 17x9.5 in the front with 265/40/17 tires and 18x10.5 for the rears going with either a 285/35/18 DR or a 295/35 or 305/35/18 my car is a 02' WS6 with a little over 400rwhp so which adapters are best any info is appreciated 
use an adapter not a spacer, adapter will be a one piece design with lugs (I've used motorsport-tech without any issues and they can anodize them). Put the wheels at a 40mm offset and they will be perfect without sticking outside of the fender.
ok cool thanks for the info and where do I go to find these?
I bought mine off eBay for 39.99. I had to use 1.5 inch adapters due to the offset. What is the offset on yours? Mine are +65mm c5 vette wheels and sit flush with the 1.5 or 38mm. I didn't cut the stock studs..

Few things...
A. If you're using ebay $39.99 adapter style spacers... you're putting a lot of trust in generic bargain priced aluminum and generice to hold your wheels on. Buy H&R's or Eibach's
Get those name brands. Ebay, who knows the quality. Adapter style spacers are taking your stud from holding your wheel on with the steel axle to hold your wheel on with aluminum an aluminum spacer and god know what studs. Better be quality
B. If you do buy those $39.99 adapter style spacers, you can press out the generic studs and just use the spacer portion with ARP studs on your car. Simple process.
For stud/spacer reference I use:
-20mm (.78") hub centric spacers
-2.5" 12x1.5 .509 knurl ARP wheels studs
-1.38" 12x1.5 Rocket Racing lug nuts
This setup get you the the stock engagement for the lugs to thread onto studs

Yes they're aluminum as well, my point is the quality of the materials. Ebay nonsense v. qlty manufacturer
now you got me worried. I agree with the quality of aluminum argument but what if I just bought new quality studs to put on the adapters. Seems safer than having the wheels bolted to the very end of a 2.5 inch stud like you have..not trying to argue just trying to figure out what's best...how long have you been running yours like that?

I'll trust my wheels being held on with ARP steel studs to my steel axle, with proper thread engagement.
so you pressed the studs from the adapter and used 2.5 inch arp studs in place of stock studs on the axle? What brand of adapter did you get?

This setup is perfect for thread engagement
OEM stud 1.63" (41.5mm)
https://www.summitracing.com/parts/r...t/model/camaro
ARP 2.5"(63.5mm)
https://www.summitracing.com/parts/a...7708/overview/
63.5-41.5 = 2mm more thread engagement than stock with 20mm spacer and 2.5" ARP studs...
So if you're using a 1.5" spacer you'll need 41.5+38.1= 79.6mm which is 3.13"... so it's splitting hairs, but you'd be at less thread engagement more than stock.
I ran the $39.99 eBay adapter spacers for about a year which included trips to the drag strip and on the interstate etc... and had no problems at all , I can’t remember what brand they was.. but 98-02 fbody is 70.3 or 70.5 center bore I can’t remember now which it is . I ran 1.5” so I didn’t have to cut down the studs in the rear and the wheels stuck out about 1/4 in. To far ,you could do 1.25 and just cut down the non treaded part of the stud . The wheels were oem c5 18x9.5 with bfg 295 Tire
