BC coilovers for the GT4, yes its for the GT4 Options

[Wolf_tm]

Hi Wolf. I dont have that problem. I have much more then 4mm. Over 1CM in fact.

I have 8J wide supertourismo's though. Offset is 35.
What wheels do you have and what's the offset?

Hi Ray,
I have Volk TE37 17" 8JJ et38... so you have 3mm more...

How do you find these coilovers compared to Tein SS. I had Tein SS on my car for a very short time but had to remove them. They may be good for track but on typical Irish back roads I spent most of my time avoiding bumps and potholes. Is there full travel on these shocks and what are the roads like where you live in Italy?

I didn't like Tein SS, but this is for sure because my car is 85 kgs lighter in the front...
that's why I removed them and I went to install this BC, I still have to use...
Yes, full travel.

Italian mountain roads, where I use it, are turny and bumpy... we will see how they are...

Received a mail from BC racing:
for them 4mm clearance is ok, so no problem...

[Mercer]

What is the ride height adjustablity like, i see uve got it set in the picture after installation. can it go lower??

[VinT]

yellowchinaman, please post something about riding on BC coilovers ) are you satisfied?

[nics]

isnt it that megan racing coilovers are rebranded BC coilovers?

i have to find that post again from a different forum.

btw, how much does these go for?

edit: BC stands for Bor-Chuann racing?

Yeah its Bor-Chuann, and they have made coilovers for different brands as a subcontractor, probably for megan too.

mines just came, and are ready to be installed!

you have to weld the front shocks to the superstrut arm. There's a thread somewhere but its not easy to do it yourself and unless you know how to weld.

Honestly not sure what you want to know (this is topic about BCs for ST205 = they must fit). And... BC is name of the brand... unless you ask where BC is from. It's British company. http://www.bc-racing.co.uk/

And... if you are asking about "plug-and-play" solution you have only two options. TEIN or TRD. Any other company (BC included) that makes coilovers for ST205 requires welding on it.






note: I have them on my ST205 and can say they are the best option for ST205 (IMO)

digging this old thread....

thanks Ray for the great write up!

i'll be getting my hand on these coilovers soon, but a quick question for those ST202/205 hybrids:

what spring rates are best for this setup.....mine is essentially ST205 @ front and ST202 at the back, would an 8K front, 4K rear work?

i noticed BC sells two models

1. C-26 94-99 CELICA (SUPERSTRUT) ST205 comes with different spring rate options
(6K-4K)
(8K-5K)
(8K-6K)
(9K-7K)
(10K-6K)
http://www.bc-racing.co.uk/c-bcc26/toyota-...perstrut-94-99/

2. C-33 94-99 CELICA(SUPERSTRUT) ST202 (8K front, 4K rear)

and im also not sure if the fronts sets are same just with a different spring rates for the ST205 and 202 respectively?

im loving my Bc coilovers, awesome in everyway! stiff but comfy awesome cornering in the gt4!

[yellowchinaman]

wow. Didnt think this thread was still going on.
Ok so about my BC's. They're still working 100% and I'm very happy. My only thoughts are that I wish they had released adjustable top mounts for the rears from the start. It would had helped a lot.
Secondly regarding spring rates. I would personally go for the (9K-7K) given teh second time round. At the moment with what I have is that it practically feels very comfortable and very able handling and cornering. (9K-7K)
would had be a bit harder which I think if you're going coilovers, you may as well go the extra mile for a race upgrade.

Now over the years, (3 years now?) the only fault I've had is that the paint on my springs had started to flake and crack off exposing it. Not that bad considering the high milage use of my car and full-o-sh1t pot holes we have here in the UK roads.
I think I'll just end up taking them apart and cleaning them up and uprating the springs when that happens.

REgarding the weld join. no problems what so ever. I have had the occasion where I've jumped and thought my car was gonna smash to bits but it still turned out fine. No hair line cracks what so ever.

Clearance with alloys? Well I no longer have the supertourismo's any more but 18 Revolutions which has no problem what so ever.

My only issue is that the allen key bolts for the top mounts are a bit rubbish because they store water and rust.
I've changed mine to SS hex bolts before they break.

Zeus. Regardingyour question, the 202 versions are literally the same but with a different spring load weight not as high as ST205.

[zeus83]

glad to hear your positive feedback guys!

so Ray, 3 years of no rebuild?

well i might opt for higher K for the fronts....9 or 10K but ST202 rear is light scared the 5K-7K is too stiff and bumpy....will opt for the stock 4K (my TRDs now are 10K and 6K at the back...damn uncomfy)

i hope guys with similar setup share the stories here

one last Q for u Ray....what weld did the shop use...cause im gonna DIY myself..

Cheers!
Sam

[yellowchinaman]

I had a friend use Mig weld on them and it was only about 3 spots of 2 cm's not all the way round. After welding, we immediately sprayed it with paint to prevent it from rusting. Till this day it looks as good as day 1.

[zeus83]

cool!

but mind me asking, why not weld all round and what went wrong in your first weld? (mentioned that instructions were the other way around?)

btw, My BC are on the way now :-)

so will keep everyone posted on this hybrid ST202/05 setup!

[zeus83]

ok...lets start!

First of all thanks to Ray aka YCM for this informative write up!

Getting the Coilovers



cutting the Kayaba NEW SR



Grinding and filing



Welding the BC inserts



Spray painting the Lower ARM+BC Inserts



Straight forward rear shocks installation



and installing the fronts set....workshop had some pain removing my old TRD's they had to take the whole lower strut



notice the welding



and finally...adjusting the camber



the Shocks were way better that the TRDs i had....im IMPRESSED!

[delusionz]

Hi Ray !!!

As I fitted them too, what about your rear BC - rear tyres clearance ?!?

I found mine to be VERY VERY small with 235/40-17, unfortunately...

I have about 2mm clearance on the left side and 4mm clearance on the right side (??) - 205/55-16 OZ Crono 16x8 et38

[BonzaiCelica]

i'm still stumped as to how these are installed. you'll need to remove the 'base' of your stock suspension in order to fit these? how are you supposed to do that?

Its teh bottom legs of the superstrut which is costing a lot of money to make. Thats why D2, G Force, K Sport etc all offers coilover which is inserted into the legs like chaning the hydrolics. But this give a very short travel. Only 3 inchs I believe which is rubbish. Only TRD and Tein make a full superstrut coilover.
This one isdifferent because it requires you to cut the legs down to the bottom and they offer a bigger and logercoilover which in inserted in by about 2 inches and welded onto the stock legs.
This allows thefull travel of the full coilover like TRD and Tein but at less then half the cost.
Look at the first page and you'll understand

I think that has to be done only for the super strut suspension, for normal McPherson that's not needed.

Correct.

I had a bit of set back. The used legs donated to me had broken top ball joints so I need to order them first.

YO YELLOWCHINAMAN can you elaborate on the other lower end companies that make the inserts for the superstrut coilovers. I saw a member selling ksport coilover inserted into the housing of oem superstrut shocks. I asked him to take pics but he never posted more detailed ones of them. perhaps he'll sne me something over soon

also are trd and tein coilovers lower than your current set up due to the fact that they come as a full coilover vs the BC's you installed
