Suspension mods for an R34 GTT

Hey Guys,

What suspension mods would you recommend doing on an R34 GTT to improve the handling, currently the only suspension mods i have are some BC coilovers.

The car is my daily, it doesnt see any track use, just some spirited driving outside town around the windy roads where i live.

Good tyres would make the biggest difference if you don't have some already

Tein or similar castor rods with pillow ball front joints.  Far and away the best thing you can do to the front end.

Poly upper arm bushes are a good thing at the front.  Get them with adjustability to be able to tweak the camber.

At the rear it is a tougher thing.  There is no point in only doing a little bit.  Once you consider changing one arm, it becomes an all or nothing sort of thing.  But minimally, bin the HICAS and put in a proper eliminator kit.  With a good alignment.

After that, you're looking at the next "minimal" thing being to put adjustable poly bushes in all the upper arms.

After that....it's fully adjustable arms up top, with rubber outer bushes or even pillowballs if you give no fark for police attention and NVH.  But that it overkill for a streeter.

The worst thing you can do is put pillow ball front joints in the car.  It will change it so that every bump you go over will be amplified through the chassis and annoy the hell out of you.  So don't do it.  Other radius arms are fine without such joints also - nothing wrong with bushes.

If you want to do something get good spring rates and good dampers and match them to sway bars.  Good alignment (including ride height), low unsprung weight and no HICAS is about as good as you can hope for.

As was said in the first reply - good tyres make a huge difference.

I still maintain that on front castor rods you can barely tell that they're there (from an NVH perspective) but that they work a million times better than even stiff urethane bushes.

I agree that they make life hard anywhere else.

I have an R34 GTT with Cusco tension rods (pillow ball) and the increase in NVH was honestly negligible

In saying that, I wouldn't be putting pillow ball bushes anywhere else on my car.

What djr said. No need to go crazy on spring rates. Get them matched to dampers along with some swaybars.

Bin the BC junk and put something that's half decent in there. 

Bushes! The more of these you change, the better. It's definitely a case of "oh wow, I didn't realise how bad it was" until you start replacing them OR changing arms that have new bushes in them. It is basically a 20 year old car. They're going to be flogged! Alloy rear cradle collars is a great place to start. The difference just by doing that is huge!

* Every arm on my own car is Pillow Ball and it's nothing like you guys are describing. You would hardly know!
