I read somewhere there was a 5Zigen FN01R also, is this true?
If so, what is the difference?
Helena has descided on this style wheel in the silver finish for her white SOHC 3000.
Can someone please tell me exactly what will fit the car.
I know we want to go larger diameter than the stock 16's.
We were thinking 18", but have no idea what width will fit under the car properly.
Once we determine what width, we will need to figuire out the backspacing.
If someone knows these magic numbers we would be very grateful.

I have a hard time believing that 18- 9.5's will fit under the car without rubbing like mad.
If the 8.5's will fit what backspacing is required?
And what bolt measurement 5- 114 or 100?
I know they'll work in the back, not sure about up front. I have no idea why you'd want them on a non-turbo though - they'll just weigh you down! Unsprung rotating mass is BAD!! :p

I know 275/35/18 tires will fit up front on a 9" wide rim, I don't see why they wouldn't on a 9.5" rim. And I'm not sure what you mean by backspacing - I'm assuming offset. 35mm will work fine, Matt (soclose3kgt) had 18x9.5's w/ 35mm offset on his '95 SL.

Hope I've helped! :)

oops, forgot to mention, 5x114.3 is what you want. ;)

Lawdogg: Haha, the google search probly didn't work b/c the cast versions are vastly more popular than the racing-forged ones (so google will just fill in the "-C" part for you).

Helena: I would also consider the 17in version. If you take a look at my sig, my car has the 17x9in FN01R-C's with 255/40/17's. The spoke style of the car and the low(er) profile tires give the effect of a bigger rim.

I'd really condsider it because 17in wheels/tires are much more wallet-friendly, and are more widely available. You could stick on 275's on those 17's for $100's less than a comparable 18in tire. The price gap is huge between 17in and 18in.

IMO, the wheel's design really optimizes @ 17in. The wheels are only about 17-18lbs wheread the 18's start to reach 20-22lbs.

Just throwin' in my $.02

Will consider the 17's, thanks. I assume that we need to keep the overall height the same as stock to keep from throwing off the speedo, Is this correct or can I go bigger? I want to get rid of more wheel gap. The intrax cut the gap almost in half.

Law..I can't believe this wheel is any heavier than the stock cast tri diamond wheel on the car so I am confused as to your comment on rotating mass.

Backspacing is a term we used with our old muscle to determine how much wheel you could fit UNDER the car without rubbing the innerfender with the tire. It is a measurement from the inside wheel lip/bead to the backside of the hub.
Thanks for all your input. Wheels are a relatively costly upgrade and we don't want to make an expensive mistake.

Check out this site to find out how far off your speedo will be with your new tires, whichever size you choose to go with. I don't know what size tires came on your car - but it likely won't be a huge difference. You can go bigger if you want - it's only your speedo. :p If you know it's off by a few % what's the big deal?? :)

You're right that intrax will cut the gap wayyy down - that's what I'm running and I cant even fit two fingers in the gap up front.

My comment about rotating mass was just a comment in case you wanted to think about the performance implications of a heavier rim ... and your stock rims, though cast, are still Al as are all 3/S rims. :)

Sorry to not understang the backspacing reference - but now I know!! :)

A bigger wheel decrease the car's acceleration though correct? I was curious as to whether this is a big difference or not, especially if the wheels are lighter than stock. Just a thought.
If you actually go with a larger overall diameter then you might get a noticeable decrease in power, but as long as you stick with the stock overall diameter and go with a lighter wheel then you should if anything get an increase in power because you are decreasing the rotating mass that needs to get moving.
