Progressive rate springs-- was coilovers, epoxy, etc...

[amalventano at sc.rr.com (Allyn)]

ok, heres the only situation that progressives may have problems.
autocross type cornering - talking about coming off the brakes as you steer
hard on very grippy pavement. basically the max possible load on a front
corner of the car. i have managed to 'pop' a coil during these maneuvers
(the close coils get to the point where they are stacked on eachother -
metal on metal, and if too much more force is applied, one of the coil
layers might roll over the next coil momentarily).

this is something i've only done once in nearly 8 years of use on these
springs, but i figured i'd give you the skinny.

agressive driving - they are perfect
all out autocross - might want to go with stiffer springs, but keep in mind
that it will be *very* stuff on normal driving.

> So, from the litte research I've done, Neuspeed is the only company that
makes progressive springs? And Neuspeed springs are no longer made by H&R
correct?  Can the new Neuspeed product be trusted as much as the old?  I'm
very close to actually purchasing a set of springs. I was going to go with
H&R Sports, but I've heard on multiple occasions that progressives are the
way to go without going to coil-overs...
