D2 coilovers

[eg-iain]

Has i saw a post back on my wanted thread i can see someone said that people have had issues with these coilovers. Now i have heard mixed reports over the years about them good and bad but what do you think?

If not can someone give me another option to d2's that lower 90mil plus, i was looking into bc's but i'm not sure they will be low enough for my liking

Thanks

D2 and bc are cheap as you like for a few resons poor materials, no development behind them i could go on and on, take my advise you get what you pay for, imo theres no better than a set of teins

I heard BC's were fine, d2's had leaking issues but were sorted awhile back.

I think I'm right in saying the BC's are made in the same factory as the apexi coilover's and the quality is excellent.

If I was in the market for coilovers I'd buy BC

BTW I have a set of d2's on my mk1.

mate who ever told you that is talkingh out of there bum, let me guesse the bc rep told you that some ones been telling porkies i think.

they are manafatured in taiwan buddy and i can assure you that isnt were the apexi sets are made, the reason they are soo cheap compaired to others are for a lot of reasons, rearly didnt want to go in to thgis but here goes

that wasnt a generalisation on all industries, that was a very specific comment on dampers. Taiwanese and Chinese production is improving all the time, most stuff gets outsourced now anyway. but that simply isnt the case with dampers, which is what i am talking about.

European brands, japanease and American brands too, such as Ohlins, Koni, KW, Bilstein, Penske,HKS, Dynamics/Multimatic,Tein,cusco Sachs, JRZ, GAZ, etc all utilise European/American design, development and manufacture. the quality is high, sometimes so are the prices.

D2, KSport, Megan, F2, G4, HSD, BC Racing, etc are all designed, "developed" (i say it in inverted commas because there isnt any car-specific testing and development, which is why the damping is so poor) and manufactured in Taiwan and China. the problems arent a function of poor manufacturing standards, which is what you have read into my comments. they are a function of the people designing them having no idea what damping a car requires for good performance, comfort and durability, and targeting profits over quality. the top European and American brands have a long history in dampers, and that is the difference in quality and performance.

the easiest way to summarise it is to say that a UK company could make a television, and a Taiwanese company could make one that was just as good. but if a Taiwanese company tried to build a Formula 1 car the same as the Brawn GP from this season they would fail, miserably. the reason being that there is decades of knowledge and experience behind the success of an F1 team, and the same applies to the components on the car (e.g. dampers in this case). you cant just manufacture something based on simple ideas and visual appearance and expect it to perform the same as the products from companies that have been doing it for decades at the highest levels of motorsport (which is where pretty much ALL of the major development occurs). what kind of serious motorsport does Taiwan have?

BCs are quite popular in the VAG world so they must be good?

i understand what your saying but bc have had a rolling evolutions documented on mr2oc i believe where any issue has been addressed and free replacements of any parts has been provided ie the droplink issue being resolved.

hsd are miles ahead of anything like k-sport or d2 and although they may be made in what you consider a lesser technologicaly experienced country have been tried and tested with uk drivers in mind. They are not the track specification coilover that come out of japan, with high damper rates and stiff springs, these require much higher quality and expensive parts. they are street designed meaning lower cost requirement in manufacturing hence the cheaper prices to us. They will not satisfy a knowlegable track driver but will a daily driver who may take his car for the odd track day.

i think what we should be more concerned about is why the op is interested in possibly dropping his car 90mm as the car will be almost inoperable at these heights. You may as well put a piece of steel bar in place with rubber bushings!

Hey there,

I get what your saying but I have not just plucked this out of the air, I genuinely can't find any bad feedback's posted regarding the quality of the BC units. I suggest asking the opinion of someone like Rogue motorsport as they stock many different setups and will have 1st hand experience of them all.

As for apexi's coilovers being made in taiwan I can find many posts supporting this and a few denying this. It seems some lines may well of been made in taiwan but probably not all.

As for the design experience argument its mostly true, but a lot of UK (/any other nation) design talent can be purchased. For example in the design of the mk1 mr2 its thought a lotus engineer was brought in as an advisor for the handling. Its a very common practice and this would negate that lack of expertise.

For my money, I'd be buying Koni's, bilstein or Ohlin's never heard a bad word said about either. I've been told by a few experts that a lot of the jap stuff never really works on less than perfect surfaces.
