Thanks. Still a lot of small things to go. Took her for another drive Saturday evening with two other adults in the car with me. She hammered with instant torque. 4th at 100km/h, I just dropped the foot and she launched. In a tunnel at 100km/h, I dropped it to 3rd and floored it, wheel spin and it sounded like an F1 car (from the 70's) as it hammered to 8,000rpm. She is an absolute weapon!

Brakes will make a difference for sure. front brace (and rear brace) make a big difference on the e24 chassis, so does some adjustment to the geometry (if you haven't done so as yet). I've had pretty good success with the Yokohama AD08R tyres on the 500+rwhp 540i. They really hook up well in the dry, and are pretty quiet, and wet grip is pretty good. Less hardcore than the 050's but won't have dropoff with heat cycles. I'm going to try the supposedly better AD09 tyres on the E24 shortly.

Glad to see it going so nice

I did a bit of research on tyres. The Advan AD09 is meant to be a hot street/track tyre. Really the most track a track tyre can be and still be street legal. I've read a few articles written by boy racers who swear by these tyres. And, they are the stock tyre for the World Time Attack Championships. So it will be a set of these next Month. I'm really risking something bad with so much power and my 15 year old glass slippers. So good call Gaz. A set will be on next month.
