Unfortunately that view seems to be looking at the front to rear view of the top mount so we don't see how far back they are, but to put it into perspective, to fit the Gaz max caster top mount, you had to shave metal from the rear of the suspension mounting top mount cut out in the chassis!

I think Si (Suba) had them fitted to his coupe so could contribute to the mounting of them.

I did a little calculation, you'd have to lower the suspension approximately 6" to get a 1' shift in caster. I'm no mafs eggspurt but I think I got it right. It would sure look bad ass but you'd be going through a new exhaust every day.

Oh wait, the damper on the right has the other view, you can see the caster quite clearly.

Agreed - the centre line of the damper rod is WAY behind the centre line of the topmount on the Gaz kit

I've chased Balance Motorsport by email today to get them to chase the BC factory for an update

In the meantime, I thought I'd do some more research to see if anyone else is having issues with BC

Lancer boys aren't impressed - check out the photo part way down the page

Sadly, it appears not to be an isolated incident....

Fairly old thread though, so I guess BC have sorted the issue by now?

UPDATE - I've had a response from Balance - they have supplied me with a technical drawing of the BC topmounts and suggested that I should tell them what changes need to be made, and they will look into having some made.

I think this is a good point for me to hand this line of enquiry over to one of the BC coilover customers - I really don't want to be acting as middle-man if I can help it

Any volunteers?

DOH! - Not Balance - Apex

I thought you were interested in buying a set Nigel?

I was, but I'll wait until the issues have been addressed (or I'll bite the bullet and go for the Gaz setup)

with the Gaz kit dont you have to modify the chassis at some point like the D" kit which is what put me off.

reading the evo post has made me think twice about ordering the fronts now

Yes, you have to cut front suspension turrets

such a shame i dont want to cut mine if i can help it. Hope the issues with the BC's are solved

I wouldn't worry too much, you are just elongating the hole in the chassis for the damper mounting. If you keep the profile of the original rounded hole then it won't cause any stress or cracks.

So what would the risk be if I mount the BC kit that I've recently got? I've posted a pic with the top mounts and they are asymmetrical.

There's no risk, you may not run as much caster as a standard coupe which would give you less steer ahead if you release the steering wheel. The car may be slightly less stable with less steering feel/weight.

You can still pull the camber in from the top mounts but that's almost working back to front, you'd want less camber with the wheels straight ahead and more when the wheels turned which is where caster is king.

Would less castor cause more torque steer?

I don't believe so, although less caster makes the self-centring effect less pronounced, which means you can FEEL the torque-steer more easily

Torque steer is caused by many things, but is rooted in a difference of grip between the driven wheels (which could be tyre deflection, surface, driveshaft twisting, geometry etc)

I guess the only time caster could affect torque-steer is if the caster was different on each side

Scroll down to caster, while it may not directly cause torque steer, the symptoms may be similar in extreme cases.

Confirmed then. It's definitely squirming and pulling on uneven surfaces now since fitting these coilovers.

You have about 2.5 degrees positive caster, so you shouldn't really be getting any caster-related squirming - does it happen on and off the power and on a steady throttle?

BTW, did you guys see Deltapart's review of the current BC Racing coilovers? I was looking to buy a set but now... No ducking way. https://www.facebook.com/delta.parts.3/videos/448819618633450/

I never used the softest setting on the rear (for the road/track) so no problem for me.

Hi, can you tell me how much adjustment is needed to get the ground clearance to be the same height as the original?
Is it difficult to reach later to adjust the rear shocks once they are installed?
