Default Good Cheap Drag wheels - 09-12-2014, 06:28 AM

So I was racking my head on what wheels to get and I stumbled upon these bad boys. They are corvette c5 wheels 17x8.5 Ofset 56. The wheels are very light because I do belive these are the magnesium ones. They fit great all I had to do was drill the center bore out abit.









little street test lol. These wheels are very cheap to buy and easy to find. I paid 340 for these two with the hoosiers on them.

Lmk what you guys think

Fantastic find

I would say put some Anthracite Plasti dip on 'em to match your fronts - and make it look almost stockish on the line.

Yeah...those and the "Speedline" 5 spokes are magnesium. And can usually be had for around $250-$300 a pair on eBay all the time and come in 17s and 18s.

We are not 5x4.75, the lugs will not seat correctly on those wheels even though they will bolt on.

Get some style 68 bmw wheels, they will fit properly and are the same size

Studs dont change the fact that the lug does not sit fully in the countersunk hole on the wheel, which results in enormous shear and lateral load being placed on the bolts because only 35% of the lug (on one side only) ends up touching the wheel mounting surface. Everything always holds great, until it doesnt.

The Corvette wheels are a 5x120.65mm (4.75in) pattern. That 0.65mm "divided" by 5 lugs is going to introduce minute shear and lateral load differences into the stud/bolt.

Hold your finger and your thumb as close together as you possibly can without them actually touching...or stack 6 sheets of printer paper together...that's the difference we are talking about here.
