Is anyone using the adjustable rear trailing arm bushes?

Rear Trailing Arm Offset Flange Cotton Reel Bush &
2.75mm offset Stainless Steel Tube, Camber & Toe Adjustable

I've been having some ECU / fueling issues today. Massive over-fueling and despite huge flame outs on over-run - which look good but hardly ideal - I have re-fitted a standard ECU / chip. It still seems to be a bit rich though so am guessing the AFM might need some attention? Am I correct in thinking I can re tension the spring if I move the wheel around on its mount? I know some people say that it's not possible to do anything with them once they start playing up but know it can be done somehow.

I found adjustable rear bushs did not give enough adjustment on my car, the lower you go the more adjustment you need

Should I combine them with the kit from Ireland Jason?

I would use one or the other it depends how much you need to adjsut the rear.

Well I got the mounts above for free so will try them first. I imagine fitting them will be fun?

Fitting can be fun as if you follow the bmw procedure for eccentric bushes you need to calculate the required angle to fit the bush as once you fit it it does not want to rotate.

Also toe kills the tyre more than camber

ive bought some camber plates... while the suspension is off i figured it would be wise. im going to order the non adjustable bushes from superflex.

i didnt get camber plates for free.. i had to pay £50 for some. defo need them im gonna be riding pretty low.

Superflex sent me a bag of goodies today. The TCA bushes are from Jason.



Spending the day @ Northampton Motorsport tomorrow and then next week RPM will be fitting the brake upgrade.

Good day at Northampton Motorsport.

Corner weighted the car and did wheel alignment etc etc.

F/N/S F/O/S
300.5 315


R/N/S R/O/S
261.5 265.5

49.5% weight distribution

Total weight - 1141.5 Kg

Managed to sort the fueling issues and reverted back to standard ECU chip prior to fitting Schrick 290* cam.

168.3 bhp @ 6 100rpm

172.4 lb ft torque @ 3 700

The torque curve is nice and flat between 3000 and 5 200 and the engine pulls really cleanly. Considering it's a stock engine and well over 20 years old I am well pleased wth the results. As soon as I work out how to get my scanner working I'll post the print-out.

mark didnt you say your car was pushing out 200 bhp once? how comes your pushing out 168.3 bhp, what happened to the rest?

The last dyno it went on supposedly gave 186 I think it was? I'll try and find the print-out but after today Im not convinced it was accurate.
Have gone right through the whole inlet side and checked for air leaks etc and sorted a problem with the barn door in the AFM. It was over fueling at idle and also high in the rev band but it's pretty much spot on right through now.
I've had to go back to standard ECU chip as the Racing Dynamics one has fried along with the ECU it was in? I tried the chip I got from you last year too but just couldn't get it to run right either. In the end, it was just easier to revert to standard until I can bin the Motronic all together.

at least you know where you stand regarding power ect... i say mine has 240bhp but i really need to get it on the rollers to see whats what before i can back that "claim up" i'll proberly find its less than standard
As to weight distrubution thats pretty spot on.

Nowt wrong with motronic even with a new cam just get it custom remaped.

You would be lucky to get a stand alone for less than £750 by the time you fit it and sort the wiring.

Sal at evolve done back to back testing on a stock engine with motronic and stand alone without the airflow meter and found about 4bhp at the top end and how offten are you on WOT.

Spend the dosh on a six brach buy the stripped 323i on ebay swap the manifolds and sell it again
