250 Adjustable Top Mounts for B14's

Be aware that the spring diameter of Bilstein B14 is much bigger than on coilovers (KW for instance). Most top mounts won´t fit to foreign struts and if you make it fit by modifing, theres less space to shift the strut aside to get more camber due to the bigger spring diameter. It will hit the spring turret. Supposedly not more than 1° is possible. To generate 2° camber you have to shift the top mount about 24 mm to the engine bay.

 

If you're after a set of BC's speak to us, we also offer a comprehensive fitting and set-up service which comes highly recommended, received this message earlier this week from @evojkp ;

"Afternoon,

Just wanted to drop you a bit feedback on the coilovers.

Had my first track session last night since you fitted them and dear o dear what a difference. I was blown away with the handling. It was a reverse session at Knockhill which makes the circuit more technical and the car just 'lapped' it up. I was catching much quicker machinery in the twisty sections and an Ohlins 275 cup 's' could not live with it, which was a good comparison as I was on track with that car before and I could not keep up in the same sections. So smiles all round.

I also noticed a difference on the way home after the session, like the car has totally settled now. That's maybe just my imagination.

Again a big thanks mate...

regards, John"

if you need any info just let me know

 

Group buy ????

 

What BC's did John fit, be interesting to see what you think in 6 months time. I had a set on my race Impreza a few years ago and they were absolutely shocking. They had zero droop, they would stick if they were set anywhere near hard on rebound, the bearings in the top mounts didn't last long. At the time Kenny Brown in Glasgow who is highly respected, was setting the car up and said "at the end of the season ttake them off and throw them in the bin". The Subaru forums are full of guys with bad experiences of them. If your car is a Road car they will corrode badly very quickly. I have had a fair few dampers over the years and apart from a competition set of AST/Whiteline dampers which were good but expensive by far the best set of dampers I have had were KW Clubsports the build quality is superb and they just work so well.

 

We see quite a lot of people complain about them, but 95% of the time it's because the spring rate has been spec'd wrong or they've been installed incorrectly.

Not to try and knock anybody elses work, but all sets of BC's have adjustable levels of droop and pre-load, so if you had no droop they were set-up very wrongly!

We also get a lot of people judge them because they're built in Taiwan not in a German or Dutch factory but genuinely the quality is good and not to be knocked, don't get me wrong compare them to the likes of KW, AST, Nitron or any high end suspension manufacturer back to back and yes they do fall behind in certain areas but for the price they're unbeatable by a big margin.

I imagine if you're racing they'll need servicing and rebuilding a lot yes as really that's not what they're designed for, even the higher end ones are still built to a certain budget so if you compare them to Nitrons or KW's at double the price then they're going to fall behind, but a well spec'd and set-up set of BC's are awesome!

 

Lol they were not set up incorrectly and I take offence to that insinuation. The spring rates were changed several times, I was fortunate enough to have my car set up by some very talented and knowledgeable companies. Perhaps you could tell me how the droop is adjusted on them ?

 

Which model Impreza did you have and what sort of racing were you doing?

It wasn't meant offensively in the slightest, it's just that one thing BC offer over even some higher end suspension kits (which we also sell and set-up on the regular) is the flexibility when it comes to droop and pre-load settings so I'm quite confused as to why you couldn't get the car set-up with some droop but I'll explain with the following;

The ride height of the car and the spring pre-load can be adjusted completely independently on BC's, so if you have zero droop you're either running too much pre-load or springs that are too stiff to provide droop, the easiest way to increase droop is to back the spring pre-load off, if you need/want some pre-load but also want to drop the height of the car you can do so completely independently, so there's no reason why you should never be able to get your droop set-up perfectly - unless you're rallying in which case BC's are the complete wrong choice to begin with.

There are certain mechanical limitations such as spring rates/damper travel lengths e.t.c if you're springs are too stiff to get to the correct ride height then you can't have any droop without having a spring that comes off it's perch under droop which on a racecar is never what you want, you'll also be limiting damper travel by doing this. Or unless you're running an awful lot of pre-load for whatever reason necessary then dropping the height of the car using the separate platform in which case a set off off-the shelf coilovers probably aren't the best solution as you'd need a custom set-up or at least something tailored to that specific set-up.

Most of the time having pre-load and droop at the same time is relatively pointless as you've essentially worked past the pre-load point when the car weight is taken up by the spring, so you'd normally run a no or very small amount of droop on a pre-loaded spring anyway, generally speaking especially when it comes to racing.

Also changing the spring rates too much without having the dampers re-valved can cause lots of completely separate issues.

 

Don't want to side track from the OP's original post. My point is, in my opinion and from my experience of BC's compared to a number of other dampers, the quality of the BC product is poor. I had as much droop as was possible to have, there was insufficient suspension travel for proper track use, the top mount bearings did not last and they started to stick on rebound at the rear when set to anything more than mid point towards full hard. They also showed signs of corrosion starting even though they had been on a race car for 10 months and had never seen a road. The car started out as a 1992 Type RA and these are pics of my last race last year before I broke the car. At this point it was on the Whiteline/ AST 3 way dampers. It was used initially for hills and sprints and more recently Super Lap Scotland Class A which is like time attack but based on power to weight. The car had 551 WHP and weighed 1068kg.

 

I had bcbr coilovers on the last car and it was used as a daily by previous owners and they did not have much corrosion on them. I would buy again but like the idea of kw.

 

I just sell my bc s !! and I also find them much more bad suspension!
they have no moves such as on stock suspension !!
the car constantly jumps on bumps !!rebound settings are bad
I order springs 10-7 and it feels much more softer compare to my stock cup suspension
never advise it to somebody!!!
now I want b14 kit or HR coils

 

BC's are cheep crap end of ! Anyone who peddles them does so for profit not for the benefit ofvthe customer .

 

What do you think about b14? Really better choice for road use?

 

Obviously a coilovers expert!!! For the price you can't beat BC's! You ever tried them?! I've got the DS Series on my R26, and find them great!

after you try another suspension you understand all he talking about ))

 

Wouldn't say I was an expert but have had BC's, Tein, Cusco, KW clubsports, AST 5300 3 way and a few others so do have a good idea a) how they all perform in race scenarios and b) feedback from experts who were setying my car up anx who do know what they are talking about. The statement that was made to me about the BC's was " at the end of the season take them off and throw them in the bin ". What's ur experience based on ?

ok why my 250 fills much more softer after I install BC with 10-7 springs ?
car drive like piece of .. on bad road I just can't drive because it bumps all the way
suspension don't have good rebound

 

I have had BC's on my mk2, took then out of the box and fitted them, never had them set up, adjusted the ride height that was it, liked them so much i bought a set for my mk3, i had these fitted and set up properly at CGR and i'm more impressed with them than the mk2 ones.

You can adjust the spring tension and the ride height, sounds like you never pre tensioned the springs.

 

and the B14's aren't adjustable, or are they ????

 

Definitely not! Stupidly cheap tho! [emoji23]

Why?
all I asks about it say they are pretty good for daily driving and little bit stiffer over there cup suspension!!
I want it not for track mate

 

maybe nut I think b14 or something like that will be better for daily

 

The only thing I looking on some coilovers. I find like the way it lowers at hr spring or some other. Back sits Lower over front ((

 

And I really surprised about damping of b14.

 

Jamie
what will give me a stiffer front Arb?
I order new cup dampers and grams springs from Kamracing ))

 

and I also find your post and you said that b14 great setup

"B14s are a bit stiffer than Cup setup, Spring rates themselves aint massively stiffer but the damping is better."!!

 

It turns out that even the old cup setup were better than b14?
