explain that again yellow91 plz. i put the megan UCA and thats wat was makein me hit. i raised up the front end a quarter of an inch and it fixed the problem pretty well other then deep grooves. i liked the look of the front end being lower but i hate hittin. wat else could i do to get it back low and not hit that bad?

FMLis300

Hammer into the fender well where it is hitting to create more room.

ISproject

It's the front only that hits. The SPC camber bolt hits the very top of the fender well. Who makes the roll center adjusters?

I believe the stock UCA's actually have more clearance than the Megan UA cus they're flatter compared to the Megan's no? & to explain the RCA' they basically help restore suspension travel that you have lost after you have lowered ur car to a point where it has poor ride quality. Cus the lower you are it moves the UCA's up closer to the top of the inner fender wells which causes the loud bang! noises. But when you run RCA's it helps keep the UA down from bottoming out in the top of the fender wells. Kinda hard to explain you'll just have to experience it for yourself to truely understand. I remember I ran them at max height where I was still tucking 1/4-1/2 tire in front & my car drove like butter only bottomed out on "bigg dips if not never.

Lol. You could but you'll only gain soo much clearance most likely still wouldn't be enough. Well, at least in my case it wouldn't help.

Hmm. Well I have people I go through that can possibly make RCA's for the IS300. I'm currently running them on my car but they are more like a prototype. I used one's they made for a 2nd gen GS but ended up chopping them in half since the GS suspension is a bit different than the IS's. But I can get them to take measurements on the IS & they can make legitimate RCA's for all IS300 owners in the community that need them cus they ride low daily. Note but I have defeated the purpose for them Instead of using them for better ride quality I went through & lowered my car even further with them which basically didn't help with my ride quality.

the megan UCA is square and has no bushings to damper the bounce on a bump the stock ones do and thier shape is round. would it be better to jus take them off? or do they have a purpose that i dont know of? and thanx for the in depth explination.

Yeah probably better to run without them if you want the most clearance.
Megan's are too square of shape & the adjustable bolts on top takes up space.
