Any opinion on that combo? Do you think it will work well on the long term? I'm also concerned by the height ratio, with the front diving like this I'm afraid this accentuates understeer.
Some like stiff springs and small bars, others like softer springs and bigger bars.
If you think the WR15's are too stiff, on your particular roads, don't get coilovers
The P11L have the same front spring rate as the lowered pinks, but the P11L are 15mm higher at the front.
My concern with the lowered sti pinks is the low ride height combined with the low spring rate - do you use Whiteline KCA313 or SuperPro trc0002? If not, get a kit.
Hopefully, you are using the soft front bump stops with the pinks? To maximise the very limited compression travel.
But, your front tyres might touch the wheel arches on rough roads or during hard cornering. Big bars might reduce the roll enough to stop the tyre to arch contact. You should be OK at the rear, due to the WR15 rear bump stops. If you get front tyre contact, use the clip-on spacers.
The first line of defence is normally the bump stop. But, in your case, you have to use a soft stop, with the pinks, because you have little or no compression travel. The final defence is the top spring perch hitting the strut body - this stops the strut bottoming out.
The lowered sti pinks were designed to use the very hard 60mm bump stops in the inverted struts - the lowered pinks ride on those bump stops all the time, which increases the spring rate. But, this gives a poor ride quality and more understeer.
