R33 Subframe in R32 GTS4/GTR problems

Hello all, 

I picked up a R33 rear subframe for my R32 GTS4 and was going to fit it to obtain wider track, better anti squat etc. 

What is the best way to mount the frame? Fit the offset aluminium bushes from the top down or from the bottom up? If they are fitted from the top down I'd have to get some sort of spacer to make up the difference as the 'pegs' that the frame mounts over dont have enough thread. 

I'm concerned that it may alter the geometry negatively if its mounted flush to the chassis rails not only will it be hard to mount the ATesa pumps etc. 

Has anyone done this? Or is it worth just changing the bushes in the standard frame..

Just a follow up,

the lower arms are different slightly, and the ‘nose’ of the diff sits in another type of carrier - different to the gtr/gts4 cradle. I will make 16mm aluminium spacers to fit the rear cradle into the car which will sit under the offset bushes. 

Im yet to cross the hurdle of mounting the attessa pump and ancillary parts

      Wow ELVIS. You have an....interesting approach to conversation. Did you not notice that I wasn't talking to you?

      Hello Liam - HA - somewhere in flies - possibly I have an update, but I have been so busy, projects have taken a back seat to getting business back on track.  I will let you know the outcome, but I think I am going to go for the 8HP,  CHEERS.  ELVIS

      Thanks Joshuaho96, yes - as someone else also suggested, the 8HP seems the 'smart choice' - HA - and ZERO to do with cost, but I am sure 8 speeds will be better than 6 speeds - HA - maybe.  I will purchase a new 8HP,  Thanks.  ELVIS.

      Nobody said anything about getting a "...cheap Falcon box..."- it was JUST a question about a specific transmission.  And YOU may have a problem with not enough $ - HA - I do NOT - so please keep your comments like you are some financial guru to yourself.  BUT - much appreciated re the cost of a new 8HP and I twill probably be the way I go.  Thanks.  ELVIS.

      Most people I know in the BMW world are swapping 6HPs for 8HPs. The 6HP has a big issue with one of the clutch drum bushings wearing out shockingly early which leads to them going into limp mode going into 5th/6th gear as the oil pressure loss from the worn bushing causes clutch slip. Even with the adaptations in shifting the TCU can't bump line pressure enough to keep the clutches from slipping and burning. I've personally looked at a 335d with 6HP28 with one owner and ~90k miles on it and the transmission adaptations were way out of spec and even though it nominally drove ok I'm confident it would have needed a full rebuild sooner than later. Other than that they're fine, but the 8HP doesn't really have weird issues like this to my knowledge and they're in everything these days so pulling them out of crashed cars isn't too hard.
