coz some springs maybe good/comfortable on some car platforms lets say the IS-F but not in the IS250/350
Try the ISX50 forums. I am sure they can give you a better reply. ISF's are totally different, suspension wise.

This is my main concern, I would like to "have my cake and eat it too" meaning I would like to have a nice ride and it not affect the performance of my 08 ISF. Basically my back is not in the best condition and the ride is a little rough on extended drives my back begins to give me problems. My friends stock C6 Z06 rides like a cadillac compared to my stock ISF. What are other peoples opinions on the ride quality of the Swift springs?

Requirements in returning your car should be in your lease. More than likely you'll have to put the original springs back on.

Bump....... Was considering the Swift springs, anybody else want to chime in with their experience with the Swift springs as a cheaper alternative to putting coilovers on the F?? The drop that they provide is exactly what I'm looking for 1" front and 0.6" drop in the back.

Thx

I installed the front only - I have had them for over 1 year and I love them. They ride is exactly the same as stock and I did not notice any degradation in handling.

IMO - for the street, these are a great option. Drop is perfect, ride remains the same (no bounciness at all for me) and handling is about the same.

Coilovers will always be a great choice since you can dial in your setup a little better..

ive had mines installed since 2010

front and back
ride is a little bit more harsh but cornering Is way better!

the only thing I am having a hard time is the alignment. nothing major just having a hard time dialing in to true center I guess.

Cool, how much did they cost and where did you buy them at?

curious if there a big difference in handling for those who lowered just the fronts on the swift springs vs those who lowered all 4 corners. I am lowered just in the front, but i am not a big fan of the rake look. I have gone with a 275 tire and 15mm spacer in the rear and am worried it will rub if i drop the rear to level it off. But i am more concerned about the handling than anything.

Had mine on for a few months and it's well worth the money. Aside from the tight handling, the extra bit of lowering is a nice look.

If handling is your priority, mixing aftermarket springs with OEM springs will not get you where you want to be. Front and rear springs, be they OEM or aftermarket, are designed to work as a group and not mixed and matched as you, and others, have done.

Agreed, that's where I got mine.

I went with just the fronts. Gives the car the perfect even stance. Ride is exactly the same.
