Hello, I have an RS 250 Cup and am looking to replace the swivel joints, but not looking to do it myself. I have been doing some research and saw that Aaron Autos and a forum member here under the name of Mark Black could do them at a decent price. However, these guys are too far from me as I am based in Kent. I have been asking some Renault specialists closer to where I am (not naming who they are), but they are asking for roughly £530 (for both sides and the lower ones only with genuine Renault ones) and I think that's a bit too much. So these are my questions: 1) Do you know anyone/garages based in the south east or south that would do it for around the same price as Aaron Autos or Mark Black? 2) People tend to just replace the lower ball joints or the upper ones too? 3) I saw a forum member on here selling heavy duty uprated ones, apparently they have been tested on race cars; are they worth it? https://rsmegane.com/threads/megane-250-265-275-uprated-ball-joints.16466/ Thank you!
