Picture looks a lot like the already existing coilovers made for the Coupe by D2 and K-Sport...
rumor has it that D2 and K-Sport are produced by the same manufaturer, only colour and label (and price) are different... apart from the looks they share the same working principle including the integrated pillowball top mounts..
regardless of that, I am of the opinion that this new concept is better than that of the existing coilovers of FK, KW, GAZ...

I think they can run inverted, looks like the boot clips onto the shock body. But looking at the setup looks exactly like the fitment for the coupe as they're the same as the 155, 145,6 bravo, brava etc even a multipla iirc could be wrong on that one though :lol:

I like his description of the coupe as a "sausage" very true! Looks interesting and hopefully they will get a good kit out of it. Also made me laugh at the description of the forum as "a place to waste money on useless items such as the various braces, (which add absolutely nothing to the strength of the already stiff body shell)" Hope Nigel doesn't read it ![shocked shocked](/forum/images/graemlins/default/shocked.gif)

It makes me wonder about the depth of his Coupe knowledge, as it's common knowledge that the Coupe bodyshell is quite flexible. Jack up one corner and try to close a door to see what I mean. Besides, the vast majority of people that have fitted lower braces have reported a better feel to the steering, so I know who I believe....

I've been in touch with BC Racing over these as they are still in the development phase, the final problem being the damping adjuster on the rear shocks. They need to be in the top of the shock : We are struggling to be able to install it in such a way that it can be adjusted without removing the damper from the car, there is little space and the adjuster must be at the upper part of the damper I've asked if I can be of any help and they have replied with If you or FCCUK members have pictures of damper adjusters on other brands of coilovers for the rear that would be helpful So if anyone does have some photo's post them up here or drop me a PM and I'll give you my email address.

AST have them in the lower eye as an upside down design. Can they not invert their dampers to have the adjuster on the unsrung end?

@Jonone - default rates have been picked, but there will be scope to easily change the front rate. I'll look up what front rate we used, it works really well I was driving the car on Tuesday. We tested 2 rear springs, and have settled on a 6kg/mm, I have the details somewhere of the first one we tested but it was a little soft. We aim to make the car refined with the default rate, suitable for fast road and occasional trackday use, rather than all-out track/race settings as this is what most people actually want from a coilover We cannot put the damper adjuster on the bottom of the damper when we use a monotube design, this is normal for twin-tube dampers. However we can install the damper upside down, which is what we are currently testing to see if there are any adverse effects. The design is different to when we last tested running a damper upside down and hope we wont have the same side effect of noise that was present with the older design. We are going to slightly tweak the rear damping rates as the current rates do not match the front (you have to have the back a lot harder than the front to get the right balance) And then we should be about done and ready to launch the kit. It will cost £699 You can achieve standard rideheight with the rear adjuster on the highest setting with a good drop available from that max height. What sort of max drop would you guys want?

Current Spring rate under test is 6kg/mm front and rear.
That's ~336lbs/in

It sounds like its going to be a good kit and I agree most people want a fast road rather than all out track day kit. I have the gaz coilovers and funny enough I have settled on 325lb rear and 300lb front and was thinking of going 325lb all round or maybe 350lb rear and 325lb front? so its nice for someone else to have come up with similar rates ![smile smile](/forum/images/graemlins/default/smile.gif) and also its nice for someone else not to have the rates front bias, I was feeling like an outsider! My car is at standard ride height as it's supposed to keep the wishbones at the correct angle which in theory helps with understeer, but i don't know how much difference this makes in the real world? I would say most people want there car lowered if only for looks, probably 30mm like the lowering kits is the best compromise?

With 60mm at front you will be scraping off the top layer of speed bumps I reckon!

Yep ![smile smile](/forum/images/graemlins/default/smile.gif) I probably wouldn't run it that low but it would be nice to have the option to go very low. I had my Alfa 145 that low and it was fine, just go careful over the bumps.

I'd want the possibilty to go 60mm front, 45mm rear Shouldn't be a problem, but I'll get the accurate figures too ![smile smile](/forum/images/graemlins/default/smile.gif) It sounds like its going to be a good kit and so its nice for someone else to have come up with similar rates ![smile smile](/forum/images/graemlins/default/smile.gif) and also its nice for someone else not to have the rates front bias, I was feeling like an outsider Good stuff. Worth pointing out that people wanting a front bias or more track orientated kit we can do that. Or even a 2-way adjustable external reservoir more track orientated kit we can develop that quickly and would cost £1299 - just give us a couple of months after the kit is launched to collect customer feedback on the BR kit.

Just out of interest with the good progress that is being made, have you an expected launch date for these (BR)?
Thanks

I'm hoping we'll have them for sale in August, probably late in the month. This is all looking very positive so far and it gives me a warm feeling that you're doing propper ground work into the design so we know it's a kit that's going to work straight off the shelf and not need many months of messing around to get it feeling right (I speak from experience). Thanks, however that doesn't means we wont take feedback on-board once the kit is launched if you guys have anything to add to the process. The BR kit is just adjustable on the damping, on 1 adjuster. The ER kit would be seperate bound and rebound adjustment. Typical damping curve (not car specific, this one is actually a starlet) ... well I was going to say is attached but I cant upload, I guess as I'm not a member. I'll mail it to Begbie.

Are your dampers true monotube/de Carbon type? With the valving on the piston?
