Alloy Subframe Collars

[Sambo33]

Hi all, i want to fit a set of these 'alloy subframe bushes' to my R33. my question is - how effective will these be if the factory bushes are really worn? will they still lock the subframe from any movement?

thanks in advance!

Do you drive this car on the road Sam?

Well, you won't be after you fit alloy bushes

cheers

its pretty harsh on the road as is. i feel every little uneven-ness in the road with my coilovers. i dont really want to go to all the effort of completely replacing the factory bushes, and ive heard mixed opinions on pineapples, with some people reporting they dont make a lot of difference? ive heard the same about alloy bushes, apparently they are effective but cause increased NVH, although ive read a few people say they arent that bad?? any other opinions?

think about it. U are now connecting the rear suspension via metal to the chassis. If u think the aftermarket coilovers u have now are harsh, add more NVH on top.

Only solution is either to replace the std silicone filled mounts, fit Noltec subframe mounts, or fit poly pinapples. Noltec ones add a little bit on NVH due to the stiffer urethane used, but it is a way better solution than alloy spacer bushes.

Speak to Shaun, as hes fitted the Noltec ones to Freebaggins r33.

Not the same car but I fitted Urethane ones to my HR31 rear subframe and fark me it made the car way harsher. If you had some fair decent rates in your coilovers and metal bushes in the subframe I wouldnt want to be in the car for more than 30mins of daily driving.

I run metal ones in my r32 with all the rear suspension bushes in poly and 5kg/mm rear springs.

It's fine, there is still some rubber between the top collar and the floor

and the more solid feel of the back end was worth any minor increase in NVH in my opinion. If i had a mechanical diff it may be a different story though...

i didn't notice any more harshness when adding pineapples...

[Sambo33]

hmm, many different opinions on this topic.. same goes for all the topics i have searched through. it seems most people who have fitted alloy mounts claim that they are not that bad. im not sure what to do. it seems my stock bushes are very worn. im stuck in a situation at the moment where i cant easily get my car to a workshop for the duration it takes for a full replacement. im leaning more towards the alloy ones for the fact that there is no more movement in the frame, and i can install them myself.

Sambo,

If your bushes aren't leaking throw the pineapples in. If they are... Best option is to go a full bush replacement pineapples to angle the cradle to provide traction or how ever you want it setup.

We run alloy subframe collars with minimal increase in noise and vibration. The main issue we have had since fitting then is that the previously sweet 2 way plated diff has now become pretty grabby in tight turns
