The springs were set at 5mm when BC sent them back to me. Still the same. I opted for 2mm preload for easier ride and to try and soften the banging.

Does the spring run close enough to the shock body that it could touch? Take it you've seen no witness marks?

Just seems odd. Plenty of clearance to the wheel as you've got 9.5's, and these reduce that gap over a plain shock absorber?

Im unsure what you mean? The spring and shocker are one unit and spring cant touch the shocker body.

The shocker DID hit the wheel as i was running over -4 camber but thats sorted now (donkeys set my car up remember)

My point is that a spring deflects in other directions as it moves. Just wondered if it could be coming into contact with something and making the noise.

If it has an internalike problem I find it difficult that it could be heard unless there was a catastrophic failure.

Whenot they came back, did you remove a spring, set then to full soft and see how they feel through the full range of motion.

The spring preload nut was tight so spring couldnt move about. I fitted them back on after BC themselves had tinkered with it. I just fitted them back on mate.

I have had the car off the road for too long getting this looked at and there are no obvious issues. Had to leave it at that as couldnt get an answer from BC.

FunkyPower even checked it out at their HQ and said suspension and arms seem fine. They did point to rear caliper slides worn which could cause banging. I changed them as they were worn but still the same.

End result. Weird

If i soften the shocks up the less banging so it aint that bad.....except that i prefer the suspension set to hard ;)

I can live with it!

Well, they've arrived and according to the instructions are preloaded, to between 2-3mm. I'll probably just leave them there for the moment and see how I find them. I won't be getting them fitted until nearer Easter. I've got my MOT at the end of the month and I've got self levelling headlamps! The self levelling system's not compatible with coil overs, so will be tinkering with that and just want to get the MOT sorted first, so I don't feel under pressure to bodge something quickly.

Yeah, according to the instructions the top hat camber adjustment is fitted on "certain models" where relevant to the car... I understand now that the top camber isn't really relevant with the Honda setup, so I guess that's why they don't include the camber top plates. I don't mind they don't have top plates, as like you said, they wouldn't do anything if they were there.

 

On one hand, the listing on the website says it has top mounts, which is annoying as it's a Honda Accord specific listing (unless there's some small print I didn't notice - which there probably is!).

 

I'll drop them an email and point out the fact it's not clearly advertised on their site. Misleading even.

In ref to the 2-3mm setup from factory....BC UK told me that none of their coilovers come set up and that needs to be done after fitment.

So nothing is black and white

Yeah... I'm going to take to a garage who are comfortable to install and tweak the setup once it's on.

You'd really need to have it cornerweighted for a proper static setup.

Wether or not the damping setup's anywhere near right will take experimentation in the real world however.

Probably best to start in the middle and go from there. Try going 4 clicks out each way first to work out which direction you want to take your adjustments in, then try 2 clicks at a time using the same bit of road till you find something you're happy with.
(It- get to the point it starts to get worse, then go back 2 to where you previously were)

If it has both comp and rebound adjustment, you'll want to do rebound first, then compression afterwards, as the circuits do influence each other.

A slower rebound will increase traction for low speed suspension travel events, and more for high speed events (sharper bumps / bigger hits)
The more rebound damping, the slower the wheel returns, and vice-versa, so less damping pushes the wheel back into the ground faster.

Most people dont bother coner weighting.but its a must really. When i first had my buddyclub coilovers they car just wanted to pull left all the time.i had it corner weighted and it sorted the issue.but iirc cost me 60 to 80 pounds. Another reason i used koni shocks and eibach springs

My usual, local indie wasn't willing to install coilies. He's a really nice old chap and has sorted me out many times with good work. We talked it through and he concluded that he thinks I'd be better off finding a garage more experienced with modified cars as he doesn't have a geometry machine and hasn't done a coil over install for a very long time. He wasn't confident he'd get me the best balance and setup.

 

So off I went to google and I found a small garage here in Eastbourne that specialises in modified cars. Interestingly on their website gallery I see cars that I often see around Eastbourne. Nice looking vehicles. Spoke to the guy there, really nice, helpful chap. Familiar with coil overs, familiar with BC Racing coil overs. We discussed ways to make sure the self levelling headlamp system could be adapted to work with the coil overs too (the level/angle sensor for the self levelling system is attached to the shock absorber). He seems like the pragmatic, slightly imaginative mechanic I need. He also does cool builds and is very familiar with working on Civics and S2Ks, so I'm confident he's going to do a good job. I'm all booked in for Wednesday for the install and a four wheel geometry setup. Am very excited!

Good luck with the suspension, looks like you've done homework on who to do your install.

I went with a reputable company in Scotland that build and set up rally cars for the last 30 odd years......

....they messed up my car as he couldnt get his head around the word 'stanced' :(

That's frustrating. This chap is about my age (early 30s), works on mostly Japanese and German performance cars, organises road trips for his customers to all go to Nurburgring together in the cars that he's worked on and seems very in tune with the modified car scene judging by the way he talks and the type of work he does.

Does sound like he knows what he is doing.

Well i have learned the expensive way as my car has been to 3 different companies for arch work and suspension setups! At least next time, i will know who to take it too.

Look forward to the pics of it after ;)

Car went in this morning, but I've already got it back without them fitted  :( . The bolts that run through the end of the control arm and bushes were seized to the bushes corroded. The first bolt snapped so they didn't touch the other. They managed to weld it locked in place so I can drive the car, and I've ordered replacement parts, hopefully should have them by Friday, so it's looking like next week now. Hey ho... this is life, keeping an older car on the road I guess. Bolts will seize, bushes will corrode.

Yep, control arm inner bolts were a pig to remove in my accord. Got one out by using enough heat to shift it, but not so much I torched the bush. The other i had to resort to cutting out. Total nightmare.

I have one free and one seized in the rear too. If it needs rear LCAs at any point I'll be on for another few hours of inventing new curse words.
