just as it states. i have the kyb gr2's in the garage , the progress rear sway bar , slotted drill rotors , progress springs. how much of a difference is made with the endlinks? i know some of you have 20's , 19's and 18's but i ride 22's and i cant and dont get on the gas to try and take a turn at 50mph so is this a upgrade that will be a benefit or a waste of money?

 

get em when your stock ones fall off or break. i personally love mine and i run on 17's for the track and 18's for dailys. they make a nice difference

 

how complicated is it to change endlinks?

 

Not bad at all. Racingline has instructions on their website.

 

About as complicated as writing your post...
Ive had mine for about 5 years, love them. they do get a creaking noise after a while and need to be lubricated every once in a while
