Yes I have read that IS300 Is heavier!
But I thought the shocks should be the same as its same chasis and shape!
But I was quite lucky to get OEM shocks (front) from Ebay front for £45 all in incl delivery, and KYB Gas £108 all in (rears)!
I still feel those front shocks from Ebay OEM were just too cheap ill have to wait and see when they arrive!
But thats the prob when U see something too cheap you queastion it and the quality, but when they are expensive you moan!
However they are much cheaper than what Lexus Reading quoted me £326 for front shocks! £326 for rears!!!
Can you believe the rip off!!!!
