I used condor speed shop bushings, great product, but their shipping takes forever through usps, so order with time lol

got all but the front control arm bushings done and new rear brake lines, as you can see the old bushings were done!

I lucked out dropping the subframe, it came out with all on its own.

little heat to remove the subframe bushings, and had the tool for doing the arm bushings

canadian tire sells pre flared lines in the perfect length for the small lines off the rear T and the longer arm lines, just had to make the bends

got the car finished friday at 2am, missed all the other e30's going to TMP, but made Tedfest

the car handles much better now, and feel alot better its capable of putting down the power it dyno'd at Bimmercruise

I am thinking of having another dyno done to see how much power was lost through worn rubber bushings

I can't imagine that changing RTABs and sub frame bushings would change your dyno readings. The car is ratcheted down on the dyno, and the suspension will only compress slightly as the car loads up, but the rollers on the dyno are smooth so there's nothing to upset the suspension.

Putting the power down through a corner on an uneven road... that's where you'll notice a difference.

Engine, trans and diff bushing were all done too, and was referencing more, they dyno owner said factor 18% for the driveline in this car, compaired to 10% for a solid axle set up, I want to too see if there is a difference.

8% difference between IRS and SRA seems a bit far fetched IMO. I'm trying to picture swapping a SRA onto my E30 and gaining 15whp...that's significant. There's no way the back end of an IRS car is that inefficient. The only way I can see that happening would be if you were running the CV joints at some ridiculous angle.

I'd believe something like 2-4% losses is more realistic.

Call they guy who owns the dyno that was at Bimmercruise and talk to him, he is the one who told me 18% loss factor. I felt it was a bit high myself, but he is the dyno expert and sure he knows more then most of us.

25th would probably be best for me, gives me time to swap my oil pump.

FYI August 17th is BMW Trillium auto-x @ TMP and then open lapping after until 5pm.
I probably won't be able to get out again this month I'm booked up with other things.

Rich, what size piping is the current exhaust? Any plans to change/upgrade it? That single pipe looks rather small for what you are running.
