How much more stiff or harsh do they make the ride?

 

Guess it depends where you're coming from. On SMOOTH pavement (nearly non-existent in CA), I didn't find the yellow car uncomfortable at all with zero rubber in the suspension + 3-4X OE spring rate + RA1s + Recaro shell with zero padding.

 

You won't notice the difference. Especially since you're running stiffly sprung JIC coil overs.

Communication between the car and road is a two way street, anything that nails down your inputs will also echo what the road is saying.

On bad roads there will be a lot more feedback into the chassis, some find this disagreeable.

 

Think I'll risk it and put them on. Pretty easily reversible, and should pay for itself in a season or 2 by holding the alignment better, it seems.

Thx all.
