Fixing Suspension Geometry In A Low Skyline

Hey there I was wondering if anyone could help me out with the dilemma I'm faced with. I have a low r33 gtst and love the "flush" look I currently have. With lowering my car substantially I have also noticed that my steering has gone downhill. My questions are:

1. I have seen people use solid subframe risers like the ones from MAX, are these a good solution or just a band-aid fix?

2. What is needed to fix the front suspension geometry?

3. Should I just raise my car?

Thanks in advance.

You're going to need to explain it better, "my steering has gone down hill" says literally nothing about the problem you're having.

Do you mean your car still rolls?

Back kicks out more?

Doesn't steer straight?

Scrubbing?

Gonna have to be more specific mate...

My question is really aimed towards fixing suspension geometry by raising both the rear sub frame and front LCA. I believe this is the root of the problem.

well you have front camber goin on, overly lowered cars generally wont handle as well as properly lowered cars that have been aligned well..

so have you got:

adjustable camber bushes front and rear

adjustable castor (not a necessity but can help)

Im guessin if you dial out some of the camber your wheels will scrub, so raise the car and get a correct alignment... or better offset rims thinner rims (so you can fit them under the guard once you lower it that far) and lower it again... but lack of tyre width will reduce grip a tad.

Hey thanks Brentton, although I'm in NSW.

For the people that are suggesting wheel alignments and the like.. I really don't think you've caught onto what I'm talking about.

What I'm talking about is along the lines of re-drilling the lower control arm / castor arm up higher to correct geometry.

If anyone has done this to their car please shed some insight onto what exactly is needed to do.

Another place I鈥檝e heard of that is highly recommended is Hassam (I think that the way its spelt) and im pretty shore they are in syd.

Ask in the NSW section for a recommended suspension specialist.

Its Heasman, they're awesome

the car feels less responsive and generally feels less direct when being pushed.

This has a lot to do with alignment, lowering your car will put alignment out of spec, (more -ve camber, excessive toe in) get an alignment done and go from there

if you want to change the position of your lower control arm to correct roll centre, you can do this with adjustable urethane bushes, but you can only raise it so much

you're still better off raising the car to the right ride height for this

You have rooted the geometry of the chassis by excessive lowering.

You can fart arse around trying to correct roll center, bump steer etc etc but it will never be right without re designing the geometry and fabricating new pick up points and arms.

NO alignment or bush changes are going to correct the issues you have created. I specialize in suspension geometry design and correction for circuit racing, it is possible but costly to rectify properly.

Keep in mind if you wanna fix the geometry you're probably going to have to modify the upper arm as well...

I know nisskid was toying with the idea of putting basically an S14 front setup in his R32... not sure how far he researched into that though.

      Mistakes were made, my R34 Story

      HPA do an interesting video on tuning, and Adrian shows on the dyno, moving from 10:1 to 12:1 (And I think even 13:1) and the power moves SFA. However, a couple of degrees of timing has a HUGE impact. Exhaust side of things will more be the length of the exhaust and how many bends and turns you have. The straighter you can keep it, the better. By a lot. Oh, and getting the diameter right. Bigger isn't always better. Going to big can actually lose you power.

      I have to say, most people I see on the road fit the bill of atrocious drivers. Whether they be cowboys in their dual cabs, bogans in the Commodores, or the soccer mums. Pretty much most people on the road put zero freaking thought into driving. Barely look further up the road then the end of their bonnet, and have never even thought about how catastrophically wrong shit can go, by doing what they all deem as normal driving. Especially their late braking, racing to stopped lights, and sitting half a foot off the bumper of the car in front at 110km/h. Wanna know what's even better? By the time their kids get to be old enough to learn to drive, they've already got in the back of their brain what is normal driving, how annoyed you're allowed to get at people etc, and then their parents who actually have zero freaking skill at driving (Even though they constantly say "I've been driving for 20 years and never had an accident!") teach the little twerps how to drive, or should I say, how to make a car move. Literally watched a parent teach their L Plater, on a 4 lane freeway, that you just slam the brakes on, and push your way over, even with a B Double bearing down on you, and that's how you should drive, rather then, just keep going to the next exit. Same shit happens all the time for side streets etc, watching numpties pull dumb shit turns pushing across 3 lanes of traffic, rather than just go up the road another 30 seconds, and take the next turn that'll get you to the same location... Oh, and the damn right lane bandits. Or the retards driving along with their headphones in, and can't hear the ambulance or fire truck right up their ass about to run them over...   Pretty much, people drive on the road, like ego centric f**ks, and don't actually think how dumb shit their driving is, how it could easily kill them or someone else in a split second, or at the very least, how they're driving is contributing to all the shit they're bitching about on the road, like shitty congestion!
