Hey all,

I have a CRX that I primarily drag race but also occasionally autocross. I do drive it on the street but I don't drive it daily so I don't care about ride harshness all that much. I have 24.5" slicks on Lenso VPDs, and the suspension on the car is so bad I can't manage better than a 1.9 60'.

Just wondering,
a) Is there a minimum/maximum spring rate that the Koni Yellows can "successfully" dampen without asking the shock to do too much,

b) What type of spring rates would be "recommended" for my setup - I see the Omni coilovers running 18k rears with 12k fronts which I translate as something like 220/350 lbs FR. Why are these so light - I was considering 500/600 lbs FR, and my friend's HB is running a 500/700 combo,

c) Where are racers getting their higher spring rates from - all the package deals I see are in the 250-350 lb range.

Thanks guys... just trying to consider my options and learn a bit more about a "good" suspension setup

 

b) Since you drag race, you are going to want some really stiff rear springs. I would recommend somewhere in the 700 lb/in range. And your conversions from kg/mm to lb/in are WAY OFF! 18k = 1007.98 lb/in and 12k = 671.96 lb/in.

c)Those really soft springs are all OTS GC springs. Most people opt for custom rate springs where you can get whatever rate springs you want/need.

 

Ahhh, I didn't know you could get the packages with custom rates... thanks for the conversions too, that helps a lot

 

remember Koni sports are valved for 550 Lbs so your gonna need to get them re-valved unless you have the race shocks.

 

I would get the Race valving Its like SSP or something along those lines. You can get custom springrates as well check the marketplace for some good deals on a package deal.

 

OK thanks! I didn't know that, that's what I was looking for

 

my crx is running 450lbs front / 800 lbs rear on koni yellows

 

And how is that working out for you? Your post doesn't really help the OP all that much.
