Coilovers? Weight jacks? Or stay the same?

My setup right now is KYB shocks and eibach sport line springs all the way around. Also have spohn a-arms and founders strut towers. I love the stance but the ride is not very forgiving! I was wondering if I switched to a coilovers conversion kit or a weight jack setup would the ride be better? This car is a street car with maybe a drag strip visit once or twice a year. Let me know what you think? Thanks

Did you mean KYB? If so they are probably bottoming out on every major bump. The sport lines have a low spring rate combined with a low stance. Your car is probably bouncing too much over every road imperfection.

If you went with the weight jack set up and ran higher spring rates combined with better S&S you would have a much better ride... The higher spring rates and better valved S&S would keep you off your bumpstops.

A coilover kit should be able to run lower spring rates; which would net a better ride quality in general. The coilover set up is more for a drag car than a corner carver.

Re: Coilovers? Weight jacks? Or stay the same?

You usually run a lower rate spring on a coilovers because of the location of the spring. The effective rate is not different from a comparable conventional spring In The stock location.

But yes, you are mostly likely bottoming out. Not a fan of the sportlines.

I learned something. I honestly didn't know that...

Another plus for the weight jacks is they are considerably cheaper than a coil over conversion. This combined with being able to dial in the ride height you want (with a re-alignment of course); and being able to run an appropriate spring rate makes them one of the better options out there.

Re: Coilovers? Weight jacks? Or stay the same?

The brand would be your choice.

Is your cars weight roughly the same as from the factory? Or have you cut down/ added on a lot of weight to the vehicle?

A very vague spring rate option would be 850lbs front / 170lbs rear. This spring rate option is widely held as good for a street / track car.

The above spring rates sticks to the 5:1 ratio. (850÷5=170)

If for example you have a ton of weight added in the back of your vehicle from heavy subs then your rear spring rate may need to come up. (were talking 100+ lbs of weight added.)

I am building an ls engine right now so that should lighten up the front end. Besides that everything is about stock.
