looking to get a tubular k member for the new ls1 t56 swap im doing this winter.. i want to go coil over all the way around and was wondering what what # coil over spring i should get... spohn offers with the k member kit a pro tour #300 pro tour #325 and a pro tour #350 ... anyone ever try or have these spring? i want to handle nice and tight yet still have a nice ride.. car will see mostly street abuse but will see track from time to time.. will not see bad weather... that what hondas are for.. im going completely spohn suspension from Kmember to panhard bar.. everything they offer.. not all at once but threw out the winter im going to try and piece it all together and get it on there.. so please any input would be helpfull.. also what would u recomend between chrome moly or mild steel.. whats the differience??? i dont mind spending the extra money on the chome moly if its that big of a differience.. will be putting up a build thread of the swap and suspension build.. so stay tuned lol

 

if its not leaning more toward a drag setup, i would pass on the front coil overs and stick with conventional springs, or if you want adjustablilty, look into Ground controls weight jack setup.

I had the front coilover setup for a while, and while it worked fine, it was noisy occasionally depending on the alignment. Too much in any one direction and the spring would sometimes rub the opening in the strut tower and bang around. I was using 325lb springs, and that was more than enough for an iron block/aluminum headed SBC.

only difference with chromeoly would be some weight savings, since the parts are usually made fomr lighter gauge tubing. Honestly, you will most likely never even come close to noticing a difference in the car with either material. I would just stick with mild steel IMHO.

 

everyone talks so highly of the coil over suspension and with me wanting to get into autoX racing i figured this would be the best way to do so.. ive always wanted an air ride system for the sure fact of not scraping paint going into and out of driveways and other uneven ground.. and for the ride quality.. but with wanting to do auto x that isnt an option.. not that the car will see the track every weekend or anywhere near that probably only a few times a year.. anyone else have any opinons on the coil over suspension??? and as for the chrom moly vs. mild steel i would rather have strenght then light weight so thanks for all the info and i will be sticking with the mild steel..
