Hi All,

I'm replacing all bushes for the M roadster, just wondering the stock bushes comparing with Powerflex yellow are they almost feels the same after installed?

Or I should go all of them to Powerflex black?

Car mainly for weekend drive and occasional track (4 times a year).

Does anyone heard Ridge Collar from japan? A subframe insert to strength up the chassis.

Thanks All
