I was about to list these and i'm wondering of the HKS coils are progressive or if it's just the OEM bucket for the rear springs that make it feel bouncy.

I know the car handled better with the Swift but that's not a fare comparison since I had Pilot Sports with them.

I tried going up to 20 clicks on the rear and it felt worse. It seems like it's adjusting rebound only and not compression. I turned it down to 10 and like it but I need to raise the car.

Has anyone tried this swap with either the GT or SP?

What spring rates did you have, what do you have now and how much travel do you have till you hit the bump stop ?

The HKS is 9kg/9kg and I forgot about the Swift 6 & 7's I think. I should left not touched the springs until they settled as now I have to raise the car as it's lower than the Swift was. I over tightened the front lock rings and don't want to remove the coil-overs to use spring compressors (dammit). The fronts are set to the original +15 clicks (half way) and I just turned down the rears to +5 which I am now happy with. Weird, I thought if the Roadster rear was heavier I would have to stiffen it more but it works better with the softer setting.

The handling could be the switch from Michelin Pilot Sport to Bridgestone somethings.

Yeah I would say it's a combination of the tires and dampener settings. I have the HKS Hipermax III 9kg front/rear and they feel perfect.

Could you tell me your settings and ride hight (or drop), please?
Thanks
