I am considering getting a set of coilovers. Silk Road Section RM/A8. link. The front springs are 14kg and rear 10kg. I am wondering, are they going to be too stiff for street use (occasional track use).

I have the JIC FLT2A Suspension in my GTR,it has 12kg/10kg springs,and is even on the softest setting very hard,so i think a 14kg frontspring will be far to much for roaduse,but may work very good on a flat track:smokin:

I had HKS Hipermax on mine which i believe were 10f/9r and they were far too hard for my liking and were actually not much good on anything but super smooth roads because of the lack of compliance- so i'd think that unless you only drive on flat open roads and tracks i'd think a 14kg spring would be way too hard!

one thing you might also want to consider is that a superhard front end will have your car understeering - I can't crank my front dampers to max hardness even on flat tarmac, because my car loses its immunity to that dreaded plowing as a result.

Yeah I know....but they asked me what springs to supply with the UK kits...........

We are still playing with rebound/compression and spring poundages thou . trying to get a "nice" set up. The 6 on the back is a little to hard once you wind the spring platform up to get a good ride height , maybe a 4kg/f will be better with a nice spring helper....

But there again what do I know......

I have been looking around on the internet and I have to say, most coilover setups the spring rates range from about 10Kg + up to 14Kg. There isn't much choice below that.

I have pretty much got the below to choose from.

Buddyclub Racing Spec F 12k R 12 K
Buddyclub Junior Spec F12k R 10k
JIC magic F12k R10k
Cusco Zero 2 E F12k R10k
Trust Type S F8k R6k

Opinions?

If you look in the Demon Tweeks catalogue you can spec pretty much any length/rate of 2 1/4 ID spring you like. If a coil-over set is too hard, see about buying the dampers only and sorting out your own springs.

You can buy springs made to your own specifications in any size or rate for far less than Demon Thieves will charge you ...

Granted, I used Rally Design for all my RS2000 coil spring requirements and they were working out at about £15 each. Just trying to work out how to compare their springs which are in pounds into the metric way of thinking. Not doing too well TBH. Mind you, Its a half hearted effort LOL.

Springs like most things you get what you pay for, a cheaper spring will lose it length and "spring" far quicker than a "good" quality spring.
