Default Wheel offset question

I'm looking into ordering new wheels here in the not so distant future for my 93 VR4. I found the ones I want in 18x8.5. I know stock 17's have a 46mm offset.

Now my question is. What should I order the new rims in for offset? Between all the different styles of the new rims I'm looking at,I can get the offsets in 45mm, 48mm, and 50mm offset. Would I be able to use the 45mm offset? Or would I be better to use the 48mm offset? I'd like to have them as flush with the fenders as possible.

I can also get something in a 35mm offset in a few of the styles. So what I need to know I guess is what the best offset would be

May not be important, but I'm looking into Team Dynamics brand rims from Susquehanna MotorSports - High Performance Vehicle Lighting and Competition Accessories since I get a discount through them Looking at the Drifz, City, Jade R, Pro Race 1.2, and Pro Race 2 styles. Think I've settled on the City or Jade R's though for now (eventually I'm going to buy some winter rally rims for my snow tires), but not sure if they will fit...

If it were me, I would shoot for +45mm offset. It will match what your stock rims look like right now. +38 will stick out a bit further, but will look fine as well.

My 30mm offset 17x9's are almost perfectly flush with the fenders.

Also on VR4's its not all about the offset. You can get something that is 17x9 and 46mm offset and it could possibly not clear the calipers due to spoke design.

Cool Good to know. I tried running everything through a wheel offset calculator I found online, but I don't understand it lol...I've never put aftermarket rims on my cars before so I have no clue about offset, backspacing, etc. I'm just worried about clearing the calipers and not hitting the spring perches on my ECS struts. And AFAIK that is controlled by the offset...

Suppose I can contact Team Dynamics and see what they'd recommend. They do manufacture rims for Mitsu and a bunch of the other car companies...And if worse comes to worse I can always see if they will custom cut something for me...or get wheel spacers...

Stealthee, what do you think on these in an 18x8.5 with a 45mm offset? Think they'd clear, or should I get a 35mm offset? These are the two I'm really leaning towards, mainly the Jade R's

Yea I know that. I forgot that he had a 93... did the 93 get the larger brakes? Or was it 94?

As Stealthee said, the spoke design plays a huge role in determining clearance. I thought the 93's had the smaller brakes but 93 is that PITA year where you never know Maybe they have the larger 2G brakes. If it has the smaller brakes, I would say 45mm would fit just fine. The +35 would be alright as well.

And you are right, offset plays an important role. I never pay attention to backspacing as it is just the rim size/2 +/- offset. I know that an 8.5 inch rim will fit on a 3S so it's irrelevant. Offset is all that's needed and spoke design.

93's still had the smaller brakes but they are still large and cause fitment issues. I threw some wheels on a 1g VR4 just to get it onto a tow dolly (yes I unhooked the driveshaft once I had it on ) and the wheels wouldn't clear the caliper even though they were 45mm offset due to spoke design.

Hmm. So do you guys think those 2 I posted would be ok to run in a 45mm offset (or 46mm if they will custom make a set for me), or should I run a smaller offset.

I'd like to try and get them in 17x7.5 in all honesty, so I can keep my tires the same (planning on running the stock chromies for winter for now) in case a tire goes bad, etc. The new rims are going to be strictly for summer/all season/touring type tires, and the stockers I plan on using Nokian RSi's on for winter...

I did send an email to TD about getting these rims in 17x7.5 with a 46mm offset, not sure what they are going to say. Also asked them about THESE in 17x7.5 with the right offset. They are the ones I really want, with the Jade R's being a close second, followed by the Drifz as a 3rd option. I'm planning on painting the car in the future in a 2 tone scheme (saw one on here like it, silver/grey with a black roof and pillars) and I think the City ones would look great on it with that paint scheme.

Do NOT put 7.5" wide rims on a VR4. Thats narrower than whats on a NA even.

Also don't worry about 1mm of difference in offset. To get a custom set made would make the cost ridiculous.

8 inches is minimum in my book ON AN NA. 8.5 on a VR4.

And offset matters directly with rim width. +46 mm is going to stick IN further on a thinner rim because offset is measured from the center of the rim. If you get 7.5 instead of 8.5 with +45 offset, the rim is going to stick in half an inch further. Follow?

Shoot for at least 8.5 as that is the stock size. No need to downgrade.
