Subframe Modifications For Your Track Car

[Simon-S14]

so basically derlin, or same product but different name, its harder then alliminium but also more brittle. either way... will transfer just as much NVH and do the job just the same.

hell you can use anything. the whole gain is from raising the subframe and using a stiffer bush. I have a mate who has gont the right tight arsed option and cut the top off the stock nissan bushes til its flush with frame and then welded a flat steel washer to the frame and the steel crush tube. effectivly locking it. then bolting it all back up.

works just as well. but too dodgy for my liking haha

From s14/r33 onwards the cradles have anti squat built into the subframes via pinion angle change.

Are you able to expand on this? I am very interested.

[Simon-S14]

the diff angles are slightly different when compared to the older s13 era frames. this is one of many changes that nissan made to the s14/33 and upward frames.

the best thing you could do to your 32 or s13 to get more traction woul be to fit a newer subframe to it.

lol thats a bit too dodgy for my liking aswell.. yeah downside is theyre more brittle... ahh either aluminium or those.. I'm just thinking the black ones I showed would be a bit softer. I dunno though.... I'll have a good few nights sleep to think it over only reason I'm going through all this effort to find the best is because my car is pretty low, well atleast in my opinion.

Atleast at the back..

S14 much better?

you will benifit from it thats for sure.

at that ride height all your rear arms are going to be at wack angles.. would be good to bring then back to where they should be.

[nsmo30tt]

Sorry to be such a hassle, but was that in reply to the bushes or S14 subframe

[Simon-S14]

you'll benifit from raising the 32 frame for sure

you'll defo benifit from fitting a s14 frame and then raising that... you'd have very little problems with lack of traction and car would handle a lot better.

not a straight forward swap tho.. need to make spacers that are offset as the bolt spacing is 10mm diff each side.

[nsmo30tt]

oh I see. Thanks.. no easier options.. using my diff housing..or a S14 one.. or anything of that sort? Or a picture of how you've done it?

ahh also does it matter if its a non turbo or turbo subframe I thought the turbo ones could take R200 diff's which is the same as mine (well i think so anyway)

[Simon-S14]

i have an s14, hence the bolt in s14 subframe.

the diff doesnt matter, neither does turbo or non turbo. as they are all interchangeable. you can fit your current 32 diff in a s14 subframe by using a s14 backing plate. in fact i have a 4.3 R200 diff from a 32 in my car currently.

[nsmo30tt]

awwwwesome, Thanks I think I'm done with asking questions for now.. I'll be on the hunt for a S14 rear subframe with R200 backing plate i assume

[Simon-S14]

yup and some of these made up.

thats the difference between 32 and s14 bolt spacing.

[nsmo30tt]

those look hot.. may be an easier option than looking for a backing plate

[Simon-S14]

u still need a backing plate if u wanna run your current diff in a s14 cradle tho...

[nsmo30tt]

oh cock! Okay I'll do that then.. I hope a S14 subframe is worthit

[Simon-S14]

if you use your car for daily duties ith lap cutting here and there then no it wont be.

if you push your car and use it on the track then for sure you'll notice a world of improvement

up to you to weigh it up

[Luke_ENR34]

Heres my subframe.

2 steel tubing welded in and 2 triangles for the toe arms.

[Simon-S14]

nice but bit of a waste of time as theres NO flex in those directions of the steel tubes at all

[Luke_ENR34]

Wouldnt there be movement from the diff?

[Simon-S14]

if there was i'd be worried

diff movement is conatined within the mounts. fact is the mounts on your diff where the bolts pass thro will break before the subframe flexes from diff.
