I have found a great deal on some rims and tires that I really like and have wanted for awhile but I don't know if I can make them fit a Starion. For some reason I can't keep it straight in my head trying to figure this out. I understand the concept I just can't seem to make conversion.

The rims have the following specs:

two are 18x8 +43
two are 18x9 +15

I actually want 10-11" on the rear so I was thinking about having the rear rims widened eventually.

I'm thinking that I could put the 18x9 on the front of the Starion just fine. Correct?

Then I could have the 18x8 widened by 2-3". So if I have this right in my head then 2" would put the rims at 18x10 -7 and then they should work just fine right?

Any corrections or alternate ideas would really be appreciated.

David.

This is what I'm going to putting on the Starion. Now I need to find some better center caps.

at best you could run 1" spacers all around and it'll look decent enough. stick tucked though, not really sure how flush you are trying to get.

Yeah it's not going to be easy as you think, nor is it going to be cheap to widen them, and there only going to be able to widen inward so your going to make it even harder to fit, and for the money to get them then to widen them you might as well buy rims that are atleast close to fitting or go all out and have a rim made to fit.

18X9's depending on offset, your suspension, and how low you are up front will fit with minimum work.  But ether way your going to be doing some trimming of suspension (if not alreayd cut down for coilovers), and some bashing and pulling fendders slightly.

I'm doing a 240sx rack conversion on the front with coils so I know I will be gaining an extra 1-2" of clearance on the front suspension. As for the rear I'm working on a 240sx conversion there also but I'm not sure if it will work yet or if I will gain or lose width/clearance. Either way I will be rolling the wheel wells for all the clearance possible and running coils all around one way or the other.

I'm also going to be doing a big brake kit with either brembo calipers (Cadillac CTS-V/Brembo) or Willwood calipers. I'm getting the full set of rims for $500 and I can have them widened (1-4") for less than $500 a pair shipping included. I'm just having a hard time figuring out which pair to put on the front/rear and which pair to have widened. I could also sell one pair like the 8" ones (front) and buy another pair of the rears; or vice versa.

The widening would only happen on the inside of the rim. My understanding is that 1/2 of the added width is added to the offset. Where I was off on my calculations from the first post is that spacers subtract from the offset while widening adds to the offset. So widening the 8's two inches would make them +68 and not useable. I'm thinking that the 9's on the front will work and then sell the two 8's and get another set of 9's and have them widened by 1" to 10's which should then put them at 18x10 +27 and I would have rims that will clear any caliper I want.

So if I have this correct I would have the following
FRONT 18x9 +15
REAR  18x10 +27 (rears widened by 1")

um, 18x10 +27 is still gonna need a 1" spacer to even begin to look good.

this is what a 10" wide wheel would look like with a negative 13mm offset

your 18x10 with a +27 is going to be sitting inset 40mm more than this pic

So it sounds like a 2" spacer it is. That would actually work perfect as I would be able to mount the 9" rim on the car before having it widened, play with the spacer to get just the look that I want, then measure how much clearance I actually have to make the rim as wide as possible. Sounds perfect!

I'm not a big fan of extended lugs through spacers but I have no problem with bolt on spacers. I'll have a 240sx suspension on all four corners but on my stock Starion I had a lug spin loose from the hub on me once and had to take the hub nut off through the center of the rim then take the rim with the hub still attached to a welder and have him cut lug off.  The stock front hubs have c-clips on the front of the lugs to keep them from backing out when you bump them putting a rim on. The head of the lug has a flattened head that sits flush against a ridge on the back side to keep it from turning. Mine spun in the hole probably from being over-tightened and damaged the ridge which then allowed the whole lug/stud to spin. The rear hub/stud combo has splines/knurls to keep the lug from spinning in the hub.

Thanks Patra!
