Since putting on the PSS9s many miles ago, I've cut down three tires at Homestead and would like some recommendations. The PSS9s have 35K on them. They've gotten so soft that I'm rubbing due to body roll on offramps. I could replace the PSS9 springs with something stiffer and read this NAM thread. I'm hesistant to throw them out and go to a FSD/spring combo since I have $1700 sunk in them. Some things to note: this is a DD, but I hard springs on the car at 22K miles (bought from a racer--they were on his race car.) I have camber plates and an adjustable rear sway bar to tweak things.

From the thread, it sounds like a 400/350 might be ok, but I'd like recommendations. Direct replacements would be wonderful

 

What kind and what size tires do you run?

 

Look into Swift springs.

 

I run the same tire on all four corners, no spacers. I shredded the outside of 1 Nitto NT01 225 17 45 on the rear a year or so ago, then dug grooves into 2 Conti DW 215 17 45's on the front recently.

 

If you want something daily drivable, 6k/6k (336 lbs/in front and rear) would be a good all around fun, fast, relatively comfortable set-up. Still nice on the track.

Sounds like you need an alignment too...check your toe. I prefer 0 toe, with around -1.75 camber front and -1.5 or so in the rear.

Sorry to highjack, where does one purchase swift springs? I hear nothing but good things but can't really find much on them.

Turn in concepts is a good shop for swift springs.

 

TrackWorx is also a well known vendor for Swift springs.
