Hey guys,

Ive found some wheels and I just want to ask. Ive got a 77 standard that is down for paint but Im going to go ahead and order the wheels for it. Im on a super tight budget and I just dont wanna screw up.

I will be adding 2.5 inch spindles and just one click in the back. Also, With these 17x wheels, Im going to wrap 205/45/17 tires around them.

the offsets and all that stuff I have no idea about are as follows.....

5x4.75 with a standard 4" backspace

As for the lug pattern. Im buying 5x4.75 adapters to make the wheels fit.

Any ideas or suggestions? WIll these rub? I have no idea. I think they will look badass tho with my new paint.

Thanks in advance for any help

you don't say how wide the are 17x??. i'm sure it's a minimum 7" but looking at those pics i'm guessing could be 8" or maybe more. looks like it has a pretty decent lip to it. by the time you figure in that would be pretty hard to pull off even if you had your hubs redrilled to the proper pattern i'm saying no go for sure using adapters.

saying budgets tight and buying 17" wheels kind of doesn't go together. but heres a little something to help if your dead set on it look for wheels that are marketed for front wheel drive cars. they will be in the offset range your looking for. your looking for offsets of ET40 to ET50 or more to help tuck them under.

you can make pretty much any wheel fit as long as you have the wallet to back it. narrowed front beams are so common place you can't throw a rock without hitting a supplier it seems. out back on an irs car gets a little trickier. you've only got so much room before to tuck wheels under on those cars before you have to start throwing the theory of narrowed rear torsion housing/trailing arms/axles($$$$) starts coming into the picture.

if your dead set on those. buy the wheels/tires. grab a pair/set of used 4x130 to 5x4.75 adapters. start test fitting and figuring out what needs to be changed to make them fit. figure if it's within an inch of fitting and being driveable you can have your hubs drilled and probably be ok. more than that and start figuring on a narrowed set up. for the front at least you could narrow enough that you could still use the adapters.

oh and most of the bigger parts suppliers have 5x4.75 brake stuff for your car already...ken....
