Hmmm, good to know, I didnt know custom springs were so cheap.

What shock could you pair such a stiff spring rate with? The AGX’s are not made to handle anything in that range, RS\*R TI2000’s are even to stiff at 5Kg front and 4.5kg rear. I know koni yellows can handle a fairly stiff spring but thats way stiffer then anything else on the market, What did your buyers run the springs on? and did the shocks last for any amount of time?
