Need Advise On Front Springs 1995 R33 Gtst

[Dasmbo]

Hi i have a 1995 r-33 gtst skyline i have just installed aftermarket coilover shocks with ride hight ajustment the front coil overs are Kei Office with Bestex springs they bear part no 66-178-150 when i look online the specs are

spring constant 147 n/mmacceptable load 10300 nacceptable tawami 70mmthey are 175mm free length65mm inside diameter

14mm spring metal thickness

Could someone suggest some springs that i could use with these shocks as the Bestex spings are way too hard. I have been told that the japanese allways run very ridgid suspension as there roads are much better not like the goat tracks i have to drive on sth coast N.S.W.

P.S. I had standard shocks and king springs before part no KDFL-101SL but were to low and kept scraping the inner guards with 18inch wheels this is why i have tried the aftermarket ones with height ajustment

thanks Sam...........

Any info would be greatly apprecieted as i dont think my body can handle another 400km run
