Jamesy Posted October 20, 2010 Share Posted October 20, 2010 Noticed recently that my rear BC racing coilovers are quite noisy over big/hard bumps - the fronts are very quiet, but it sounds like the rear nearside coilover bangs a bit. Does it more so when cold but is that normal? if not...whats up? thanx Link to comment Share on other sites More sharing options...
mark newman Posted October 20, 2010 Share Posted October 20, 2010 are the retaining locking rings tight, Link to comment Share on other sites More sharing options...
Lee P Posted October 20, 2010 Share Posted October 20, 2010 are the retaining locking rings tight, Yeah the rings are tight, my Tein's knock the same from cold but stop after a while. Its definitely internal noise from the shock itself. I have had a few people say the same thing about the BC, even from new. Link to comment Share on other sites More sharing options...
hackin_n_bashin Posted October 21, 2010 Share Posted October 21, 2010 I get a little noise from one of mine when i first start off, but the car is usually sat for a week or two between runs out. Did you set the dampening to softest for a while to bed them in when you fitted them? And out of curiosity, what settings are you running now, I'm just fiddling at the min with mine!!

Jamesy Posted October 21, 2010 Author Share Posted October 21, 2010 I think mine are set to medium softness.... will have a check ... its just the rear nearside one that knocks but its driving me fu(king mad!! Link to comment Share on other sites More sharing options...

The only way to sort it will be to replace the shock mate, I would give apex a call and see what they reckon but I don't think they service them.

hackin_n_bashin Posted October 21, 2010 Share Posted October 21, 2010 That's the same one as mine! Only been on the car >200 miles. I was hoping it just needed a little preload winding on, as it only happened when the cars been sat for a week, and then only the first time it moves.

hackin_n_bashin Posted October 21, 2010 Share Posted October 21, 2010 Jamesy, what do you class as medium? I've det mine to 6 clicks from softest at the front, and 3 at the rear, but still not happy with it. Can't decided whether it needs to be firmer or softer to sort it out!!

Chris Wilson Posted October 21, 2010 Share Posted October 21, 2010 Has it lost its gas charge? If so they will knock a bit and stop as they warm up. As all gas is lost they'll hammer like hell and *ugger up internally. Do they use spherical bearing top mounts? If so cheap spherical bearings will start knocking after a bit. Internally, apart from leaking, dampers can have the piston valve come loose and that will knock, too. Link to comment Share on other sites More sharing options...
tDR Posted October 21, 2010 Share Posted October 21, 2010 These BC Racing Coilovers always did sound too cheap too be good long term Anyone seen similar of the HSD's? Haven't seen any such postings yet... Link to comment Share on other sites More sharing options...
mark newman Posted October 21, 2010 Share Posted October 21, 2010 I have BC on my car no probs . great set . Link to comment Share on other sites More sharing options...
Guest Budz86 Posted October 21, 2010 Share Posted October 21, 2010 I have exactly the same problem with my BC's. Got Lee to fit them last winter and they creaked a bit at first then not a whisper out of them all spring and summer, now it's started to creak again! I have now got them set to either 9 or 11 all round I think, but when I got her back from wheels in motion they had set them to 6 or 7 Link to comment Share on other sites More sharing options...
pistonbroke Posted October 21, 2010 Share Posted October 21, 2010 My HSD's have been on the car for a few years now, *touch wood*, they're still very smooth, totally silent, and dry as a bone. I recommend them to everyone based on mine, Darron has just stuck a new set on his UK spec. The new HSD's come with adjustable pillow ball top mounts too.

Ark Posted October 21, 2010 Share Posted October 21, 2010 My HSD's have been on the car for a few years now, *touch wood*, they're still very smooth, totally silent, and dry as a bone. I recommend them to everyone based on mine, Darron has just stuck a new set on his UK spec. The new HSD's come with adjustable pillow ball top mounts too. Well, my HSDs have been adequate so far, just over one year on there, mostly track abuse, including the ring. Mind you, one of the valve adjusters has broken, and the rear nearside squeaks under compression - could need some grease on the top ball joint.

Chris Wilson Posted October 21, 2010 Share Posted October 21, 2010 The new HSD's come with adjustable pillow ball top mounts too. Adjustable top mounts would be of no use to double wishbone set ups like the MKIV though. Link to comment Share on other sites More sharing options...

pedrosixfour Posted October 22, 2010 Share Posted October 22, 2010 Fast road spec, German-made Bilsteins, a la Chris Wilson. Smugness, it's a warm blanket in the cold light of day. Link to comment Share on other sites More sharing options...

Jamesy Posted October 25, 2010 Author Share Posted October 25, 2010 mmmm, will ask Lee to check the settings again when he next has the car Link to comment Share on other sites More sharing options...
Jamesy Posted October 28, 2010 Author Share Posted October 28, 2010 Om i think im gonna bite the bullet and get a new damper for the rear....its not too expensive i guess. Lee's gonna check its not the top mount first but i cant live with the knocking anymore Link to comment Share on other sites More sharing options...
