I am building a street/track 89 turbo S and would like to upgrade my front springs to Hypercoils or other 2.5 inch springs. I believe I have to change the upper perches. Do I also have to change the lowers? Also what length springs should I buy?

I see that racer edge has the perches, are there other choices?

Paragon Products sells a kit which includes the lower perches that fits your M030 threaded sleeve, 2.5" Hypercoil springs and 2.5" spring hats.
