Has anyone installed these or know someone who has? Any insight as to quality? I found these lower the front 20mm (~0.7") and the rears 10mm (~0.4") so these look to be the mildest drop, even moreso than the Tanabes. Probably not in the interest of the majority of people here, but just wanted to see if anyone out there has them. Thanks.

 

I dont think anyone has done their springs yet. your best bet would be to look at pics of the impul car from the tokyo auto show
