: Man, after spending way too damn much money on my car, putting everything from bigger wheels to a blower on it, I finally found what I think is the best bang for the buck. I put in a 3:46 rearend and took out the stock 3:23 on my '97 ///M3-4 this past weekend. What a difference in off-the-line and mid-range performance this made. It's like a completely different car. Unlike my blower, which doesn't noticeably kick in until 5K rpm, the low-end pull from the ratio change is immediate, and cost me about 1/4 the cost of my blower.
: The other modification that I just did and highly recommend, (but probably will get me flamed or this thread pulled) is a short shift conversion, using the factory shifter from a ///M roadster. The shifts are much shorter now and the side-to-side slop has also been reduced, and all for the price of only $50.00 in parts!!!! You can't beat that, and it only took about 45' to install.
