Wow, you have been registered about a year on this forum and you never heard of Backdraft racing???
First of all, IRS is a wonderful thing especially for track. Secondly, most kits/replicas can be completed with IRS. Factory Five can be made with IRS. Unique comes standard with a Jag IRS, and on and on...
The BMW IRS is a nice set-up. The Backdraft was my choice, but if you want to duplicate the Run-N-Gun Backdraft, you'll need about $3K more than the standard car price. That car had the BMW M suspension, which is a lot more performance minded than the E-36 standard set-up.
If you are not going to race, live axle is still perfectly fine, and many people with live axle race as well.
One thing about the Backdraft that is different than most IRS cars for handling is the 92" wheelbase instead of 90". I'm not a racer, but I've been told that the 92" wheelbase does have some advantages. Maybe some comments from someone who does race can verify that statement.
If you stack up the features of the Backdraft car, from IRS, brakes, paint, etc., etc... I don't think you can get more bang for the buck anywhere else. I was going to build the Unique, but I couldn't finish it for the price of the Backdraft.
Have fun with the decisions ahead of you.
