I have some King Springs 1.5 inches lowered, heavy duty for sale. Bought for $160 will sell for 70 ono. only 6months use, they just weren't up to the job of a CA18...engine too heavy. suit a12 or a14 though. i'm in Byron Bay but can post.

I was keen until I read that they were no good for a CA18. When you say the engine is to heavy do you mean that the springs end up to low and the wheels are fouling or is the handling no good. I was told springs with 200lb rating should do the job fine, do you know what rating yours are?

I don't know what rating they are, but definately not 200lb. I went over bumps and they bottomed out! The ride was too rough aswell. with a lighter engine the springs would handle great. I went to the wreckers and found some rear springs from a commodore (i thinK) then cut them down, they work fine.

i'm interested. will they work on a sunny 310? Do you know what king spring part number they are? I need those front springs and a set of the progressive 1.5 inch lowering springs for the rear. I can't seem to get them from datrats.
