1. Are there any common problems things that break etc. for this car?
Yes, but the great thing is they are common and can be planned/corrected for and there are not a lot of them

2. What size tires can fit under it in ITR
Wheel width is 8.5" so a 225 would fit nicely and a 245 would as well and work with just a bit of fender rolling; stay close to the stock et38 offset

3. Why the allowance for a trunk mounted fuel cell is the sock tank in a dangerous location?
Very safe location. We kept the stock tank in our BMWCCA Mod class car as it is also mounted low and close to center.


4. What to junkyard replacement motors for these run?
A few hundred to a couple thousand, many to choose from though. You should be looking for a >94 as this is the VANOS motor which gives you variable intake valve timing

5. What do replacement transmission run?
About as much as a Valentine's day dinner with a nice bottle of wine

6. Are final drives and LSD easily available, what is the typical cost.
Good searching will net you a stock clutch pack type <$500. Many "is" models come with them

7. How are the brakes on the car? I don't enjoy cars that are under braked?
BMWs get flak for poor braking systems as they have stuck with the single piston slider type for years while recently most manufacturers are using multiple piston, fixed calipers in their performance models. Fresh fluid, well bled, rebuild kit (rubber bits and cheap) and a good choice of pads will give you a more than adequate braking system

8. How difficult is this car to work on? What are the ECU options?
Very easy and very reliable. ECU is called a DME. Believe you can use anything that fits in the stock DME box which gives you many options. As anything, depends what you want to spend and spend some time with the rules on this one.

9. Oh yeah and how are they at making weight does a 215lb guy stand a chance in this car?
Making weight is not a problem but to fully answer your question a)Not sure how good the 215lb guy in question drives and b)I thought this was for your wife!!

10. Anything else anyone can offer?
Lots of hard development work previous done on this chasis for you to pull from. That counts for a lot.
