castor

[A1quattro]

which mod will give best results. 1/ fitting balljoints which move the wheel forward 20mm or 2/ moving the whole subframe forward by same distance this will also move wishbones , is this better than just moding the balljoints

How are you going to mod the balljonts?
Tidiest solution would involve going mad on custom suspension components and is probably not economically viable.
Modifying the turret tops to accept adjustable camber / castor plates would be easiest and give the most flexibility.
The works cars used a fixed set-back plate on the turret top to increase castor for some set-ups so this is another option.

You can swap the ball joints from left to right to get a lot of caster but the front axles will foul the chassis & the wheel will set noticeably forward in the wheelhouse, BTDT. Moving the subframe forward will give you an extra 2.0 degrees of caster or so. Using the B4 ball joint in the Coupes will give you caster gain. Custom top mounts will be needed to gain more caster than that

My top mounts and subframe bush combo achieve 20-25mm offset spread over the top and bottom of the strut, so the whewl only moves forwards a little.

I've not upgraded to eherls yet, are they really worth the money?

what are your subframe bushes as i will be looking to get some in the next 6-8 weeks am not aware of yours are they poly or solid with offset

you does know about the a-symetric wishbone?? the cast one, and the pressedsteelplate one for audi 80 diesel 91-93 ????... with 3 boltholes???

TBH I've not had the chance to fit them yet but they're offset alloy ones (solid) and are part of my project kastor development kit (3 years and counting...)

Any photos to illustrate your point ?

Thanks.

the balljoint for the servosteering are about 3-4 cm forvard....than the topmount...normally are the wishbone symetric... but s2 and diesel audi 80 from 91-93 are A-symetric... and the senter hub(20v and s2) are about 17+17 mm out, than the normal ones..
