17x9.5" with 275/40x17 all around

5.5" backspacing for the rear
5.25" for the front


This is the only info I found on Torque Thrust II rim specs when I did a search.
I want to order these for my grey 88 IROC (which will be lowered approx 1-1.5" and has drums on the back)

Can you guys confirm this is the correct specs before I make an expensive mistake?


Also, will this throw the speedo reading out?
I have the std 16" IROC rims at the moment.

 

thats correct, thats what chevyken has on his car and his car is lowered too, so thats what im gonna use for bs when i get some rims.

 

yup, as mentioned - those are the specs I use with the car lowered 1.5"

I want to be able to rotate my tires ( my cars is the everyday driver ) So do you think if i went 5.5 bs all the way around i would have a problem? Would it look weird in the front?

 

it wont look wierd, the slp ronal firehawk rims has a 5.5 bs all the way around, but they also come with a 1/5 inch spacer so that if you have a non 1le car the rims wont rub, i think you could order them in all 5.5 and see if it hits, then runs the stock rims for a while. in that time you could have a 1/4 inch spacer made at a machine shop or buy some.

 

So if I order wheels in 9.5" width I need to 5.5" backspacing for the rear, and 5.25" backspacing for the front.

And if they don't make 5.25" backspacing I can order 5.5" backspacing and use a .25" spacer?

 

Again, check the link I posted above. It is all there.
Basically most people, as far as I know, are running 5.5" around, but I prefer the extra clearance from the tie rods to prevent rubbing.
