The 225 would most likely require rolling the rear fenders, but otherwise should fit. I was trying to stay away from body mods, even though that's a fairly minor one.

There is no option to do this. A 325e runs in G Stock, an 325i/is runs in D Stock. You might as well replace the car if you're looking at doing this since it would require a complete motor change anyway. An is was produced in 87, but changing everything over just wouldn't be worth the work. And the is was only a 2 door, so if you've got a 4 door you'd be stuck anyway. Now, in Street Prepared, all E30 325s are on the same line, so if you go up to SP you could move anything from an i/is over. > Yep.

I never said the option would make sense, I just said it was there. Again, I'm no expert on e30 bmws. You absolutely can do option package conversions in stock classes. If you can make your E into an IS bmw would have delivered, its legal. Note that you also need to worry about unibody differences (often some models were only available w or w/o sunroofs, for instance, which meant the unibodies were different). See the 3rd paragraph of the beginning of section 13. And yes, its often much smarter to just replace the car (but its often not as well). > > Yep.

But STS/STX don't allow R-compounds. Please read the rules. In _STX_, a 2wd car is allowed any time of limited slip. 14.11.a.5 You are correct that STS/STX don't allow R tires. Typically for newer folks that's looked at as a benefit, not a problem, particularly given the cost and tire life of Azenis, MX's, etc. Mark ------------------------------ Date: Fri, 14 Jan 2005 09:45:47 -0800 From: [EMAIL PROTECTED] To: [email protected] Cc: [EMAIL PROTECTED] Subject: Re: E30 for SCCA Solo II Message-ID: <[EMAIL PROTECTED]> Jim, here are diffs that will fit: 2.93:1 - 1986-1988 (LSD stock) 3.25:1 - 1982-1984 533i, 1985-1988 535i/is, 1983-1984 633CSi (LSD optional, use your old cover and output flanges) 3.73:1 - 1987-1991 (or convertible thru 1993) 325is (stock LSD) or 325i/iC (optional LSD) 4.10:1 - 1988-1991 M3 (LSD stock, but ratio is too extreme for an eta) But a non-stock ratio would mean that you would not be able to run legally in G Stock.

Sometimes that's enough to make clearances work. Also note that > rolling of fenders _isn't_ allowed in stock class. In that case (no fender rolling), forget 225s. They won't fit under an E30 without rolling, no matter what offset you manage to get. The rears _will_ impact the fenders at some point. I know Alex Schipkov has managed to stuff 245/45/16 Hoosiers under an E30, but that required liberal applications of a sledge hammer to the inner fender wells and much use of a baseball bat on the fenders, and they still rub on the outside rear. Kevin Still trying to figure a good way to get 245s under my E30...gotta chase that E36 323is with a 2.8 and 285s! _____________________________________________________________ Highspeed Internet and Email by: Metronets www.metronets.net ------------------------------ Date: Fri, 14 Jan 2005 13:25:31 -0500 From: Ben Keyes <[EMAIL PROTECTED]> To: [email protected] Subject: Re: E30 for SCCA Solo II Message-ID: <[EMAIL PROTECTED]> you can also run a 3.46 from an E24, with the changes noted below.

I have a set of 225/50-14 hoosier's that I bought used from a miata guy and installed them on my stock 14x6.5 basketweaves.. and the tire rubs the front struts.. (ie: it won't work!) I haven't tried it with spacers. my 225/50-15 RA1 on kosei k1 15x7 and 225/50-15 toyo t1s on borbet 15x7 have no problems though (rear fender needed slight rolling).. but on the shorter wheel (and maybe the bulgier tire) it's a problem on the front.

Yeah, I dunno how the tire would work on the e30 specifically. My point to him was more not to be too worried about the 6" rim width. Note that stock class in SCCA allows you to have +/- 1/4" offset as well... Sometimes that's enough to make clearances work. Also note that rolling of fenders _isn't_ allowed in stock class.

The rim will be 76% of the section width. 80 to 85% (7.5 or 8 inch) is better for a 50 series tire, but 76% will do well. My guess is the 205/55 (a 7 inch rim is 81% of its section width) will provide better precision and response off center at say 0 to 0.3g lateral, but at higher cornering loads, above 0.5 g, the 225 will maintain its footprint shape and respond better. Plus the 225s look better and will last longer. You could use lower inflation with the 225s for a softer ride, but that will soften the response even more. With 6 inch rims, definitely stay with the 205s.
