ok so trying to figure out the whole coilover thing(), anyone know what the spring rates on the HPK 255 series kit are?
thanks guys

I would be worried about shock valving then spring rates.

HPK255's aren't coilovers...

Google result:

Tokico HPK255 strut/spring kit - has anyone used this setup? - HybridZ

I'm just going from memory but IIRC its 175/200

Lol I guess I should have read the thread - now I'm quoting myself. At least I wasn't out to lunch with the numbers. The rears are slightly progressive but the fronts are linear.

I have them on my car already and know they aren't coilovers, I need a starting point so that I'm not too soft in the rear; ksports are 8kg/6kg F/R so they are underrated for the rear spring rate, so I'm going to have to mix and match. this is all assuming that tokico took into account the correct suspension geometries when they built the sports springs kit

IMHO the 200lbs are too soft

nope, kinda washy

any ideas on a setup for spring rates then? going to have L28ET (240hp) dropped in sometime, and I will be continuing to autox the car, so something fairly stiff, wont be on r-comps, most likely dunlop star specs

PPK was running 550lb/in springs... said he was going to change them out for 800lb ones. Though I don't know if he ever drives his car anywhere other than to In & Out car meets. ooo003oo32h!

A quick Google-machine "serch" brings back tons of peepz saying 400-600lbs for a coil setup.

thats about what I was thinking, ok. thanks

ok been doing some looking around on the interwebs and I'm seeing 400 front and 800 rear-holy sh*t anyone know anyone who can make em that stiff?

Is yer google machine broken?

800lb coil springs - Google Search

yep its always broken when I need it; you should this by now
anyway I figured what setup Im going with -- T3 front coilover conversion at 6-7kg/mm and S13 megan track series rears at 10kg/mm
sound good? 'nuff said?

The 510 guys are running 1100lbs in a 2200lb wet car! Similar trailing arm setup as well compared to the S130

holy jeebus
