Question on Upper mounts

[ILikeMy240sx]

Is there a significant difference between NSIMO upper mounts and stock upper mounts? Im taking about the part that goes on top of strut assembly and has the bolts to attach it to the car.

Probably a stiffer rubber...maybe urethane?

[ILikeMy240sx]

yeah the description says stiffer. but performance wise.. would it make a big difference?

The reason I ask is because Im buying a Nismo S-tune coilovers and one of the bolts on the rear upper mount broke. So he replaced with a stock one.

If I run one of the rear upper mount with stock, would it really affect the car in a negative way?

they would be stiffer than stock. i wouldnt run one nismo, and one stock, just use both of either. but no combination of the above setups will change your suspension in a ground breaking way.

Its called "Derlin" it has a far higher stiffness rating than the stock rubber used in most bushings, but doesn't bind like urethane...

a great entry upgrade. Don't run the stock and Nismo ones together..bad idea.-Chet
