Good wheel spacer vendor.
I have looked on E-Bay for some hub centric spacers but Everyone has a ton of negative feedback. Does anyone have a company they have had good experience with that has a quality product?
looking to addd 4th gen wheels to front with C5 kit. 1.7" thick on a 2.77 hub.
I'd appreciate any and all feedback on this.

Re: Good wheel spacer vendor.
Been running the same ebay set of 2" adapters on an S10 for 5 years, never any trouble. We do drive the little truck rather hard, well for a 2.8/auto Dime anyway. Even been on the Dragon 6-7 times with it.

Re: Good wheel spacer vendor.
I found mine (lug-centric) on amazon. I've seen many positive reviews about Motorsport Tech, though they are a little more pricey (custom made to your specs)

Re: Good wheel spacer vendor.
This is some promising news. All the feedback I read online was horrible. I finished pressing in the new lower ball joints, C5 brakes, Koni's, and founders CC plates. My 17x9 ZR1's weren't even close to fitting without smashing the strut. Man it's getting exciting to get closer to a roller since she's been on jack stands for over a year!

Re: Good wheel spacer vendor.
Now I feel like I should warn you, some folks on here strongly recommend using hub-centric spacers rather than lug centric ones. I haven't had a problem with mine though.

Oh yes, do stay away from lug centrics. Somebody wanted a big brake kit installed, so I obliged. The rim wouldn't clear the caliper, so he installed wheel spacers. Wheels came flying off on the freeway!

Re: Good wheel spacer vendor.
I haven't had any luck finding the correct hub centric spacers.
I live just outside of Houston, so I guess I'll stop by some tire shops to see it they have them. I guess 2" should work fine with the C5 hubs and won't stick out too much.

Re: Good wheel spacer vendor.
Here's the issue.
Hub centric means the hub fits snug inside the wheel's center bore. Adapters can be hub centric to the factory hub, and adapters can have a hub centric snout on the wheel side to fit the wheel's bore.
Our hubs are ... 70.3... 70.5 something like that. If you see a number in that range in a 5x4.75 pattern, that's going to be hub centric for our cars.
The problem is that when you replace your brake rotors, you replace the hub. I dont know about everyone else' rotors, but my front hubs are definitely NOT the same 70.5mm diameter as my rear hubs. There's at least a 2mm difference in radius along with a big fillet at the base to prevent anything from sitting well around it even if I got a custom size bore. So you can get a hub centric adapter if you want, but it may not do much up front. I would suggest getting a set of 70.5mm hub spacers.
THESE are my rear adapters, they are hub centric on both sides. You can almost see the snug fit to the hub in this picture:
They fit GREAT. They are from lugs-n-stuff on ebay. Perfect fit. They seem solid to me. No complaints.
These are my fronts.... not hubcentric. I'd prefer these were at least hub centric on the wheel side. It would make wheel mounting a LOT easier, and I find that's the biggest difference between the two in a way that you notice. Mounting my front wheels I have to be very careful to slowly tighten each lug as I go around and make sure the wheel stays centered on the lugs.
They are from ez-accessory. The thickness of the adapter at the base where it mounts on the studs is very thick... I dont get a full lug nut's worth of thread engagement with these on the rear. The fronts have longer studs so no issue there, but if I were running these on the rear I'd need to change out my studs on my axles. Not a huge deal, but it's just another expense and hassle after a wheel/tire change that you just dont want to deal with.
If I buy a set of hub-centric adapters for the front, Im going with lugs-n-stuff, I just like the fit a little better and the price was slightly better. I see no huge difference in quality between the two. The other concern I had before was that if I got a hub-centric adapter on the wheel side, that it the factory hub on the front would prevent it from seating all the way.
That's a 2" adapter in the front, and as you can see, IF the rotor hub was the "correct" (?) 70.5mm, then then then a hub centric adapter would NOT be able to fit on it. You cant really see it in the pictures, but there IS a lip inside the hub bore for my rear adapters because they are hub centric on the wheel side. Regardless, they DO fit over the front hub without any problem even though they are much shorter, because the front hub diameter is small enough. So my OE factory front wheels are lug centric on the front, and hub centric on the rear. This may be part of why there's so much conflicting info about it.
Im having a REALLY hard time understanding how wheels can fly off the car using adapters. With spacers you put a lot of stress on the studs, but adapters are no different than wheels as far as the studs on either the hub or the adapter are concerned.
You can see pictures of my car with the ZR1's in my sig if you're so inclined. Im running 17x9.5 ZR1's, so they are wider than 17x9's.
Also, Ive autocrossed on these, no problem.
