I posted in Tech Talk, but received mixed answers that were more car specific than I thought the answers would be. So I'm posting the same question in the BMW section. For those of you that don't read Tech Talk, my E30 325is race car sat for 2 hours in my flooded garage. 10 inches of fresh...

I need to change my stock diff in an 89 325is to a 4.10 diff. I see them for sale from BMP for a pretty steep price. Can I visit my local junk yard and use one from a crashed M3? Would that be legal in IT? Or should I pull the one I have and have it rebuilt with the improved ratio. --Ray

Is there a resource (book, website) that would help with suspension adjustments or do I resort to trial and error? For my '89 325is, I am setting the camber at 1.8 and setting the shocks mid-way to start with. I've disconnected the rear stabilizer, but left it one the car so that I can test...

My suspension is done. I got t drive the car around the neighborhood today. The car is off to the shop for an alignment tomorrow and to put the new race tires on the rims. My region has a "once a year" tech next weekend. Hopefully all will go well and I'll be ready for the season. As for...

I'm looking at the directions from Ground Control to install the lower spring seat on the strut housing, but I'm not clear on something. The picture shows the seat being welded 3 inches from the "top" of the strut housing. Am I supposed to cut the strut housing at the weld to the stock seat or...

Anyone have suggestons on enhancing the stock brake ducting on an 89 325is? Turner and BMP both sell duct kits. Does anyone have experience in installing these. To get them on, do I need to pull the wheel bearings? Has anyone tried a "roll your own" solution by modifying the stock bcking...

I'm installing a race suspension in an '89 325is. I've completed the rear and I am now tackling the front. While I've got it in pieces, I'm also replacing the control arms. Anyone have any headaches tht I should worry about when replacing the cotrol arms? Any tips to make the job easier...

To disconnect the ABS for an SCCA race school, I pulled the sensor connection plug on the left sid of the eengine compartment and the ABS shut down. The brakes worked. I only locked them badly once or twice (I think). With the ABS disconnected in this manner, are the brakes operating...

The 2001 GCR says "coil over struts and shock absorbers, where a threaded sleeve is permanently attached to a housing, are prohitbited unless fitted as standard equipment". Can someone tell me how this prohibited coil over differs from the type of coil over I see on many cars? Does anyone have...

I ran my stock suspension on my E30 last week at Summit Point. A wild (and slow) ride to say the least. I'm shopping for a full upgrade to a race suspension. Turner sells a "J-Stock" kit for the E30 that contains "all you need" for about $1800. Does anyone have any experience with this kit...
