BMR springs or stock springs? I'm curious which spring would be best for drag racing/traction wise. I just swapped out my BMR springs in the rear for some stockers with 1.5 coils cut off. The stock springs combined with the QA1's i just installed ride nice, a lot better than the BMR's and stock shocks. I'm heading to the track this friday and i'm wanting to figure out which springs i'd benefit from the best. I previously had a 1.8 60' with the BMR's/stock shocks and i'm wanting to improve that greatly.

I have several customer run great 60" times on our springs(all the way down into the 1.teens) as well as the stockers.
What lead you to believe the springs might be the source of the 60" issue?

I was just thinking that the BMR's were stiffer than the stockers. I compared the springs last night and the BMR's feel softer than the stock springs. I pulled the stock springs this morning and put the BMR's back in and i like them combined with the QA1's. The main problem causing the poor 60' were my OEM replacement shocks. It was just an experiment but i'll know for sure tomorrow when i go to the track and test the BMR's and the QA1's.

The BMR's felt softer than the stockers??? I believe the rear BMR rates are around 160 lbs * in and the stockers are like 114 lbs * in (correct me if I'm wrong). Regardless, the stockers have softer rates. Good lowering springs, such as BMR's, increase the rates to prevent ridding on the bumpstops all the time.
