I am new to import, I have a 1991 CRX SI. My questions are, can I cut the springs on it, to make it lower? Also, my rpm's are high, but when the car warms up, it starts to go high and low rpm's...I am making this car for a race track and to drive on the street.

 

sure you can cut the springs. and worsen your ride at the same time. go for it!

as for the idle thing, sounds like a vacuum leak or bad iacv

 

yea, it sounds like your iacv, usually the seal is bad and not the iacv.

 

If you want to lower your springs DO NOT cut them as they will be a SHITTY rought ride....Buy some lowering springs...You will be better off in the long run or buy some Coilovers like KAI has advised me to do.....LOL

 

When i bought my crx, it had brand new tires and lowering springs. Now i know why they put new tires on it before they sold it. I think the front tires lasted about 10k miles before the steel belt was showing on the inner of the front tires. Sure, you can buy camber kits for these cars, but i've heard where they dont help that much in the front, which is really where it's needed if you have lowering springs. I just bought some stock springs to raise it back up. The ride is 10 times smoother(no back jarring jolts when you hit a little bump), and my tires have lasted 60k miles and still look good. You can look at the tires with the lowering spirngs, and they look like this / \ instead of this l l . That is of course without the camber kit. Oh, and by the way, i've still got the lowering springs if you'd like to buy them. I don't know what kind they are. All i know is that they are yellow.

 

whats a iacv and location? I wanted 17s on will they hit if i lower it .
