peter is right. a 10mm spacer would do the trick.

well, technically you need to only do the front, but from a looks perspective it might be a little weird, so i would suggest spacing all four corners.
8mm [www.turnermotorsport.com] 15mm for a slightly wider stance [www.turnermotorsport.com] the links for the lug bolts to be paired with the spacers are on those pages, also.

I would think that doing only the front or rear would change the tread/track and alter the steering geometry slightly. Someone as attuned to his car as Ove or Dave G might notice some adverse handling. I definitely have to agree on the looks...cars like the Ferd Tempo had a wider tread at the rear than the front and always looked weird; same with cars like the old Citroen. Wheels that form a nice rectangle seem to look best

the proper tire size for a 15 inch wheel on an e30 is 205/55-15. you can even put a 225/50-15 on there if you want a wider track. as for wheel size, you should be looking for a 15x7, 15x7.5, or even 15x8 if you want, 4x100 lug pattern, ideally with a 57.1mm centerbore (in order to avoid using hubcentric rings or hubcentric spacers, which are ok if necessary). As Dave said, the correct offset for a 15x7 wheel on an e30 is ET24 plus or minus about 4mm. for a 15x8 wheel you would need an offset lower than ET20 in order to keep the wheel from hitting the strut or shock. If you do happen to get wheels with a high offset, there is nothing wrong with spacers as long as you get them from a reputable spacer seller, like turner motorsport. Some argue that it is extra unsprung weight, but there hasn't been much proof that it makes any difference, at least for non-track driving. From a looks perspective, a correct, or low offset wheel without a spacer looks better than a high offset wheel with a spacer. just a thought. Don't worry about E36 offset, as they are all 5-lug.

that link isnt working. you should look in the r3vlimited wheel classifieds to get an idea of what is available.

Hey, those are my track wheels! I have two sets of Pro Race 1.2 wheels (same as the 1.3 but slightly heavier) for my Miata track car. They're excellent wheels. They are very popular in both the Spec Miata and Spec E30 racing worlds, because they are fairly light, strong, and relatively cheap. (Miatas and E30s use the exact same wheels, except Miatas usually run offsets of about 30-40 vs. 20-30 for E30s). They probably won't win you any car shows, but IMHO they're not bad looking. I like the fact that they're functional first and stylish second. Here's a pic of my bronze set on my Miata. (My other set is black and ugly, but I prefer them because of their smaller offset.) I think the silver ones would look pretty good on an E30. 
I've used the well-used ugly black ones on the E30, but sorry, I don't have any good pics of them. (One nice thing about having an iX is that because the iX has a stock offset of 41mm, I can swap wheels with the Miata.) The other very popular track wheel that's similar to the Team Dynamics in size, price, weight, and strength is the 15x7 Kosei K1 Racing wheel, but it's a 6-spoke wheel that looks quite a bit different. I have a set on the iX for the summer, but unfortunately I don't have any pics. Personally I like the looks of the Team Dynamics wheels better anyway. Also, you can get center caps for the Team Dynamics wheels, but not for the Koseis. That's not an issue in competition, but it is for a nice-looking set for the street. __________ Dave '91 325iX |

hehe, the link still didn't work, but i did a search for the pro race 1.3's to see what you were trying to link to. here is a set i just found on tirerack.com [www.tirerack.com] good price, lightweight, correct offset, correct centerbore, and come with centercaps.

the wheels i posted on tirerack do not have more than one lug-pattern. look closely and you will see there is only one set of lug-bolts. i think i know which RD wheels you are talking about. those are nice, but they might be kind of rare, so it might be hard to find just one for sale. The car will be influenced more by the road with a wider tire, so grooves in the road will pull your car left or right slightly more than 195 tires would, but it isnt bad or anything. technically yes, your gas mileage will be slightly worse. also, the tire patch isn't bigger, it is only a different shape. in terms of cornering, you could theoretically have better handling with a 205 compared to a 195, but with a size difference so small, tire compound is probably more important in terms of determining handling. as for the links, maybe it has something to do with our browsers? or maybe the links require having visited that site previously, or something? who knows.

yes, the wider the wheel at that offset could create rubbing issues at full lock, or make the wheel simply not fit because of interference with the strut. generally speaking, the wider the wheel, the lower the offset must be to fit...until you start running into the fender.

you shouldnt have trouble finding 195/65-14 or 205/60-14, which are the proper diameter.
|
if by correct "larger" size, you mean larger diameter, then sure, but the diameter of 215/60-14 tires is larger than the proper diameter for the e30.
