Suspensoin Bracing

[simpletool]

Can anybody share experiences of both underbody brace and strut tower brace?

This is for the R33 GTST.

Can anyone recommend a good supplier of these?

My first Skyline was a 4 door R33 GTS and I purchased a Cusco oval type strut tower for the front. It was the only suspension/body modification and it was night and day in handling. My R33 GTST has both front and rear round type Cusco strut tower bars and I am happy with them, though it would be nice to have exotic titanium strut tower bars

I think the underbody is robust enough to not need bracing, but then some cars, such as the new Subaru WRXs are known to have weak underbody bracing. But then I don't have aftermarket underbody bracing so I cannot say about how effective they are, I might get a set if someone says they are worth it.

For suppliers, maybe check Nengun or Perfectrun.

Thanks. I'm not too sure on the stiffness of the R33. I'm quite suspect on it. The R34 was apparently 100% stiffer or some such, well that was the blurb when they released them.

I think I at least need the strut brace at the front. Wondering if an under-engine brace exists?

underbody brace wise the only one i know of is the one that braces between the caster rod brackets

difference.. yes very little and not as much as a strut brace

i remember reading the r34 website on the old nissan japan site, it has a reinforced C pillar, they also mentioned that the r34 GTT chassis brace design was based on the R33 GTR, and R34 GTR is stiffer again

its true that R34 GTT and S15 do feel stiffer than R33, especially on driveways

again R33 is so big inside so naturally it won't be as stiff as an R34

S15 and R34 GTR have all sorts of funny braces from factory like the spare wheel well brace, transmission tunnel brace and rear subframe brace, sometimes it really makes you wonder if they really do anything

never really checked out the GTT so i dont know what braces they've got

The tower bracing will definitely stiffen things up.

There are also these, there is a rear under brace going around as well.

The R33 GTR has a lot more bracing through out it than the R33 GTST.

In the boot/backseat (not talking about the rear brace that is factory on S2 GTST's) and underbody from memory.

I'll try to find pics.

EDIT: No luck finding pics of the damn things i'm talking about.

I've often thought about welding some additional support to the stock sheet metal link between the strut towers and the firewall. I would think making these 2 sections wider and thicker would help a lot.

No that is NOT my strut brace - I wish it was though !!!

Seriously dont get too hung up on this stuff. Most of the braces sold do very little other than lighten your wallet and weigh down your car. Chuck a strut brace at it & leave it at that.

yeah i looked into all of this fairly recently, most places set not to bother, i ended up replacing the suspension bushes through out and that made quite a difference even though the factory bushes were still in a reasonable condition!

not sure if thats much help, but no point spending hundreds on products that do very little!
