I have got some VERY fast cars running a split spring combo...
That said, I would like to see it with BMR on all 4 corners.
The stiffer springs tend to work okay when launching cbr style (smooth slip style).....but when you start getting aggressive with the launch, you really want everything to work together.
I am telling you right now, the BMR front springs are phenomenal, especially for what you want. I wanna see them, paired with the Stranges - PRONTO! lol
I'm afraid it would look stupid with that combo. I would have to swap all 4 out I think. The sportlines are so low in the back that it would look really bad with reverse rake. Right now it sits pretty level with street tires and 'face down, ass up' with drag pack.
Text me your best price on a set of BMR springs and strange adjustables.. you know the number.. I'll run it by my accountant and see what she says..
