Peoples experiances with XYZ & BC coilovers???

[1I1]

Talking to local suspension guru. He was impressed with the quality of the BC. He commented that they were identical in their build to Tein (has played around with teins for long time). I had also heard that BC were made in the same factory as tein from another person (unsure on how acuarte that one is). Was enough to convince me to try em though especially for what you pay for a brand new set! $1250 vs $2500+ for big name brands.

[Mr Revhead]

what? no BC i've seen is the same as TEIN

[1I1]

Well i haven't pulled either apart - that is what he told me. I would say he was refering to internal assembly.

[Mr Revhead]

BC's are insert type arnt they?

[1I1]

Not sure, from their nz site

[Mr Revhead]

that no lookie like TEIN

I'm now pretty certain D2 / K-Sport are also XYZ (not to mention Megan Racing et al). Just got an email from 'Michelle' looking for 'sole distributors' in 'our region'. Oh I feel sorry for the other D2 'sole distributors' that bought into this

[Akane]

The general hearsay is that BC is made in the same factory as buddy club. Oh well.

either they are all made in the same factories or they are very good at copying each other and in doing that they copy each others mistakes just just seems a bit odd to me, or lazy. You can decide which.

just looking at them all the dimensions, shape, materials and quality are very very similar.

[THA SHZ]

haha bc's are nothing like tein if youve played with them you will notice everything , even right down to quality of materials , but bc would be the lesser of the evil of the cheaper coilovers , but bare in mind you get what you pay for , although you could do a nice set of shocks , some nice lowered springs and nolathane a few bushes for the same money and it would handle so much better than cheap coilovers
Are you going to do alot of track time , cause if you arent then coilovers really are pointless for mainly street driving

What exactly do you want out of suspension and what does the car get used for? Until people know the intended purpose all you're going to get is "don't get brand x because my mate said they're crap so therefore they are" type responses. At the end of the day if your car is just a street car you'll get more joy out of a $500 kyb/koni shock setup with good springs than a $5000 adjustable platform setup...

As for D2's - I didn't realise just how bad their reputation was. If I had known 4 years and countless hours of track time ago I would have avoided them "like the plague"

Aside from being harsh on the street (street cars shouldn't have coilovers anyway so no bother) I've got nothing bad to say about them....Every failure I've seen was due to running overly stiff spring rates that caused all the force from the road surface to be transferred to the strut body instead of the actual shock (causing broken mounts/bent & snapped struts, cracked welds, destroyed seals etc) - that sort of condition will damage any strut. Example below.





Is that the manufacturers fault or the owners fault for not researching adequate spring rates for the weight/use of their vehicle? I certainly haven't had any trouble with my D2's and they've been in my (daily driven) car for years and have been on just about every track in NZ multiple times including several bouts of surfing Pukekohe's notorious ripple strips - If they really were as bad as they're made out to be, they should have disintegrated by now. Suspension isn't an area to just "pick a brand" and go - you need to properly research what is right for the car and how it is driven. Picking up whatever coilovers fit with whatever spring rates they come with is taking an expensive gamble. Of course everyone blames the product immediately without first asking themselves if the product was right for the application in the first place. If you put diesel in a petrol engine it's not the diesel's fault when your engine is less than impressed.

Yes it is the manufacturers fault for using cheap low grade alloy in there products, if these were a well built product they should easily be able an handel a track day

Damn I've never seen a set of BC's, Teins, Drummonds, Ohlins or any brand of suspension shit its self as royally as all of those early model D2's used to.

Before I get flamed about not actually owning the product, I had a complete D2 suspension set up in my AE86 I specified the springs rates as well and it was just horrible

The replacement struts they supplied for the front were the same length as stock so when you wound the coilover's down the springs become lose almost instantly plus they didn't even supply keeper springs, you would think a company that desgins suspension would have thought about this and would have supplied short stroke shocks for the front.

Also the adjustment is horrible there is no real way to measure the level of adjustment as there was you just twist the adjustment knob there is no click to indicate that the setting level had changed so there was no real way to adjust the shocks, except of either fully on or fully off as in between it was to hard to match.

Thats my feeling from my experience's with D2 suspension

Dude jsut get a set of BC's and be done with it if you going to be tracking it alot, If its goin to be mainly street with occasional Track id jsut grap some TRD springs, Nice shocks, and do all you bushings

haha i got the same email, ive had it a few times now

yep i agreee with pete, teins and bc's are a long way apart from each other.
For the money the bc product is fair however.

[callum]

maybe my d2 coilovers wernt such a bargain then

Hmmmm D2 supply them with springs.... Have sold heaps of springs to ppl who couldn't handle the rates they came with. hows 18-20kg for a jza80? I know they are heavy but come on!

Ionic, i say your lucky, i personally come across several sets that have failed. We (autolign) we always getting asked about parts/repair of them. Cracking of the clevis is another common (and $&#$% scary) one

[FLAWLES]

i run Bc Br ( gold ) in my jzx100 and have done for close to two yrs, they are a very very nice coil over, sue me but they are well made
they have seen many a track day and my local pass, which isnt the smoothest

only issue i had at the time was i felt that the rear spring rates where abit soft, but this turns out to be just my fussy ness and a bigger sway bar sloved the problem

but like someone here has said, it comes down to what you want to use the car for,

sometimes a shock and spring set up works a treat

[frost]

bc is nothing like tein, the mounting brackets on my type flex are steal, and brackets on the BC's ive seen are alloy,(just like D2, k-sport)
tein's are quite heavy compared to the rest, even there racing class are heavy,

save your money and buy quality, its the most important part of your car after all,

[d1 mule]

i ran K sport in my old daily driven/drift ae85 and it was fine for a while but eventually got sick of the bouncyness so brought a laser as a daily. apart from the harshness on the street i had no problems with them.

my current ae70 as the D2 coilovers in when i got it and same thing, never had a problem, but i brought a parts ae85 with a nice TRD (8kg, 5.5kg)/koni adjutable setup and have swapped them in will be interesting how it goes at the track in a couple weeks

bc gold are steel, only the red are alloy from my knowledge
