Bc's 05 sti
 

My 05 sti has developed the dreaded rear shock knock.

I have been looking at Bc's and wondered what the advantage of the rm series is? and if its worth spending the extra on the er series?

The car is not a daily driver, gets used on track quite regularly and does a couple of trips to the ring a year.

look forward to everyones thoughts.

I went for the ER on my 2005 STI but only because they popped up second hand on this forum and I had a bit of an impulse moment.

Can't compare them with the BR or RM - but the ride quality is fantastic after a bit of finetuning with the rebound/compression adjustments. No proper track time on them yet (single session at Trax) but going to Cadwell next week.

I've just made a thread of my own in the last 24 hours though as I've found traces of oil on my adjuster knobs at the rear... could be nothing, but also could be a reason to stay well away :lol1:
