STEVO9000

Rears now removed again, standard suspension reinstalled. Distributor want the units back for further testing. Will keep you updated when I know more. Fear not knocking BC owners, we shall hopefully find a solution

Test carried out, knocking from both still apparent. Have contacted them back to see where to go next. Have also been doing some research, spoken with a few others who've had the problem, one who's investigating now also. As well as spoken with another retailer who has had no issues with any kit they've supplied and fitted bar one recently which was returned and rectified. So we shall wait and see!

So the advice received is to strip the unit down (remove spring and locking collars) and test the movement of the damper. I'll be hopefully doing that over the weekend. I suppose the plus point is the knock isn't getting any worse!

Scrap that, it was waiting for me when I got home! Thanks Chris, looks great! Can't wait to fit it

Bugger. Missed this post! Did you still have my address from before or do you want me to resend it Chris?

Yeah. I have read up about it on the frs forum. Just seems weird where some owners don't get it, but majority of owners do. I'll see what they advise in the week and possibly consult with my setup specialist

Just to keep you updated, Pre load added in as per their instructions and top nut also adjusted. Knocking had reduced but not totally eliminated, have fed this back and awaiting further instructions

I am in direct contact with the BC UK distributor at the moment. They've advised me on recommended preload to add, and about tightening the top screw. So I'll give that a bash over the weekend and report back!

Lucky man, I was toying with putting mine up for sale to buy that haha!

Yeah, I'm pretty sure it is just that. Would just be nice to have them clarify as like I say I know a few people have gone back with the same issue and been told it's the car. But hey ho, I'll dial some pre load in and refit. Fingers crossed

Oh yes certainly they can be adjusted that way I was just merely seeing if anyone else has had the same issue from them as they were installed as they'd come out of the box. BC's initial reply was that it was a fault with the car, something to do with a problem across the rear deck where the spot welds break and cause the panels to knock together. I removed them purely as a process of elimination exercise and so we could feed that back to BC on Monday. Hopefully adding pre load will just solve it, but I'd like to see their response first as if we go by what they tell us to do, they can't say we did something wrong

After discussions with the supplier, we agreed to take the rears off the car just to eliminate anything else. However, what I have found is that once the rear is jacked up and the wheels removed I could actually put my hand on the spring and spin it on the perch. I could also grip it and rock it back and fore slightly and as it moved you could hear a small clunk. My guess is when it's going over a bump and the shock is extending the load is coming off the spring and allowing it to move slightly resutling in the knock. Either way, they're off the car for the moment and the standard stuff is back on the rears with no knocking. So we're going to run this by BC on Monday and see what they come back with. Hopefully they agree that'll be why and we need to add some pre load to the spring as they were fitted exactly as they came out of the box with no adjustment. If they believe it to be something else then obviously it'll go back. I'm just hoping if they do say to add pre load and I put them back on that it doesn't knock! Jamie, just to check did you ever have yours properly set up with the pre load adjusted? If its not too much trouble, could I ask you to try the same on your rears? Whether the spring with turn and rocking it back and fore produces a knock? Thanks

Hmmm.....seems weird though as it was fine on standard suspension and it not as bad with the shock set to full soft. Will wait and see what BC come back with and my alignment guys say tomorrow.

I've not touched the height at all yet Jamie. I'm taking it for alignment and setup on Saturday morning so I was going to have the height adjusted then. I've spoken with the company I bought them from who are kindly querying it with BC tomorrow. Doing some googling though, appears to be a common problem for the tears not necessarily on the gt86 though but quite a few guys on the frs forum have had the same issue.

Payment now sent, should show from Mr S F Caie

Confirmed my invoice, will send payment when I get home, left my security key for my online banking there lol

Having seen your skills on everything else on your car Nige, I would well be up for one of those from you!

If Fensport dont have them, let me know. I've got a 12 plate on standard wheels/suspension at the moment I can measure up

If you find that you want to split the items, I will take the front lip off you straight away. Have been talking myself with DCw about one, I'm just not a fan of the rest. Either way, GLWS

1. Rob275 - 1xMedium-Grey, 1xMedium-Red 2. Minion - 1x Medium-Red 3. Captain Duff - 1 x XXL Red, 1 x XXL Black 4. STEVO9000 - 1x Medium - Grey

1. GTB 2. Neil_turbo 3. STEVO9000 (Chris, I'll give you payment for this aswell next week when I order my other stuff, unless you want it beforehand )

That front lip on the DCw kit is gorgeous! Shame I'm not a fan of the other parts or I'd have taken it! GLWS!

You sir are winning at life to an extreme degree. Watching this with anticipation for updates!

I'm only in Swansea, providing nothing comes up and I can make it, I may well come along

Hey there, Thought I'd join up and introduce myself, have only recently found the forum. I'm Steve, 25 from Swansea. Recently purchased myself a Black '12 plate Manual, leather/alcantara, sat nav and parking sensor equipped GT86 from the ever helpful RRG Macclesfield last month. So far I'm enjoying the experience of owning such a new car thats still so fun to drive! Previous to this I had a 230bhp Supercharged Mk2 MX5 which was extremely fun to drive so the bar was set high and so far the GT is doing well Few plans in the pipeline, mainly some wheels, lowering (still deciding between coilovers or Eibach springs, more than likely coilovers as I would like to do a few track days during my ownership), full exhaust, a remap and maybe a few aesthetic bits and pieces! I look forward to being an active member of the community
