View Full Version : Dc2 Vtir Knuckles on an EF CRX, hear me out...

So ive read and read and read and read...

I want to know if anyone out there knows if it is possible to get correct suspension geometry while using dc2 Vtir knuckles, dc2 coilovers completely sacked (skunk2 pro s 2) and adjustible everything including traction bar (camber kit, etc) on my crx without having to machine anything...

I know the camber will be out and I know the car may sit taller than desired initially but with an adjustible traction bar will the adjustment be enough to offset the added CASTER angle the vtir/itr knuckles create.

Someone has to have done it!!! Facts please!! Ive read over 20 threads worth of speculation, I want facts! Please and thankyou xx

So I heard you out, in exchange for my time do you care to share why you want to do this?

As an anecdotal piece of evidence, a friend with a DA (similar OEM knuckle geometry to EF) fitted DC2R knuckles and even with quite low ride height and negative camber adjustment (the pivoting ball joint style setup) he was still only able to get to roughly neutral camber, perhaps -0.5° at most. If you want to do it, get a pair of the DC2 knuckles, put them in a press and bend them, bam problem solved.

I have personally fitted EG knuckles onto an ED, which are essentially the same shape as DC2.

I have seen first hand the shape doesn't allow for suitable camber no matter what you do. So agree completely with what chargeR has said.

May I ask why, you say you want to fit VTiR knuckles. You can run the same disc and caliper using a set of DA9 knuckles.... What's the purpose of using the DC2 parts?

You must spread some Reputation around before giving it to chargeR again.

Its only a matter of sourcing the part really as I already have the vtir knuckles and $300 worth of brake parts on it. I dont want to sell them and id really like not to sell them as ill lose money. I figure that if I can run 0 camber but excessive caster the camber on cornering will be comfortable and work well however if it is too much trouble than its worth I understand. I think what I will do is simply try it with my setup and visually assess the situation. If the prospective 0.5o is achievable it may work, just. It all depends on the caster angle I can achieve...

Markismaximus wouldnt bending run the risk of snapping?

Unless im wrong but to my knowledge getting the caster right means I can run 0 camber and have effectively 2o camber when the wheel is turned

What brake parts? Discs, calipers, pads? All that can be transferred onto a DA9 knuckle.

Personally I would not bend a knuckle. It would weaken it, and seems pointless when there are plenty of DA9 knuckles around.

Ok well here's what ill do,, ill test out the dc2 knuckles and if they dont work ill get some other knuckles. Im gonna do it anyways and do a write up on the results!

Yes, all the above Markismaximus

Yeah agree with that for sure, I'd only bend the knuckle as an absolute last resort. Silly when you can just get a DA knuckle and fit up all the other bits from the DC2 knuckle.

Unfortunately it doesn't work like that. Caster on its own does mean that you gain camber as you turn the wheel, but unfortunately there is the effect of steering axis inclination that more than cancels this effect out for any reasonable caster number (ie. less than about 11° degrees on an unmodified EF, it will be worse with the DC2 knuckle). So more than likely you're never going to have more camber than when your wheels are pointed straight ahead.

Ok, bugger. Ill just get some da knuckles then if that will take all the dc2 stuff (calipers, rotors, bolt on no modification)??

Could you use the fast brakes adapter and all the dc2 gear on the stock ed knuckle?

scratch that the pads will be too far up the rotor, as its designed for bigger rotors.

I have 260mm brakes on ed/ef knuckle for sale.

Was used on b18c ed9 crx.

Im just getting a set of da teg knuckles, should fit sweet without wasting any money on another set of brakes.

What actual knuckles are you selling? DA or EF8?

I'm not too sure. I would assume ef8. 260mm brakes. Was on an ed9 my cousin built.

How do I tell?
