OK I kind of get you... so how do I get hold of re-inforcement for the shock mounts like you mentioned? Is it a simple kit or add on that you screw on or would it have to be welded on? I do plan to take the back seat and strip the back as I am slowly making this car my project track car so what ever option you can recommend I'll consider.

OR basically you recommend that I dont put coilovers (the HSD im getting) at the rear? What about new springs with higher spring rates?

If you're going to turn it into a track car then by all means go all out with true coilovers on the rear. For engineering of the mounting points I suggest researching G35 Driver as well as googling but yes it involves welding.

Also have a chat to Sydneykid on these forums, he is very knowledgeable with suspension requirements & setup.

Not to hi-jack the thread but whats a "True rear coil over set up" ?

A coilover design is where the spring coil is wound around (or "over", if you will) the damper body. It's the most common design used. The back of the FM platform doesn't use it, however. The coil spring sits next to the damper.

Some places get rid of this setup and put a coilover in to where the damper resides. The spring bucket then sits empty, or some peoples will delete that entire component and replace it with an adjustable arm:

After I get my tax return, I plan to get HSD HR coilovers with spring rates of 10kg front and 12kg rear and you guys got me worried talking about what Mosoto said:

"The rear mounting points are not designed to take the weight of the car unless you plan to reinforce the area."

If these are the HSD HR coilovers you're getting, then they're not a rear coilover. The damper and spring are kept separate. So it won't be a concern for you.

I got a set of sway bars for my birthday and plan to put them on with the coilovers. Will this help or worsen the situation?

I'm not sure how it'll affect the strength/weakness of a coilover conversion, but I'll give some other advice.

As for doing the swaybars, set them soft and work your way up. I fitted my bars first and had them set to full stiff with the stock Z33 springs, which had the car nicely balanced. After fitting my Teins (12kg all round) the car wanted to slide everywhere.

With your stiffer rear springs that effect is going to be even worse.

How do you adjust the ride height with a separate spring? I'm assuming you would have to swap springs to adjust it as per a conventional shock?

The aftermarket spring is shorter than the stock spring. The spring sits in the factory location with an adjustable spacer.

So when you adjust the height in the rear you have to adjust both the spring and the damper.

Thanks mate

      I swear at my GKTech ones every time I have to take them apart and replace a spherical. But I wouldn't swap them for anything else. They absolutely slay every other option, at least in terms of how they actually work. You sure you don't want to live with bearings? I mean, they don't have "ball bearings". They are rod ends and sphericals throughout. Tough as nuts, even though I have found more than one way to wear them out.

      From when I was looking at getting the 86 engineered for the turbo, the joint said to put in a few euro 5 or 6 cats, then tune the car on a nice clean E85 tune When I was looking at a turbo for the MX5, it was basically the same thing, a couple of cats and a nice clean tune Although, it will depend on the year of the Jeep IRT emmisions standards required, and what mods are done, especially if it has a newer engine installed that requires a higher Euro

      Yeah - but it's not actually that easy. There are limits for HC, CO, NOx and particulates. Particulates shouldn't be a concern in any petrol engine unless trying to comply to the very latest Euro standard. But getting a tune right so that all the others stay within limits AT THE SAME TIME is not a trivial exercise. You couldn't possibly get it right by just guessing at the tuner's dyno, unless he had a 4 gas analyser up the pipe, which is not often the case these days. It used to be. Every decent shop that did "tune ups" (as opposed to tuning) would have a 4 gas analsyer. Perhaps there's still quite a few of them around these days. But most "tuners" are only watching O2 and power readings.

      Slight segway but the most expensive part of the whole thing which I would have thought would only be required for an engine size/type swap, not a VIV test, is emissions testing.  That's when you get into the big bucks.  I can't remember the exact price now but I got quotes for the GT-R based on swapping to RB30 (not that anyone bothers doing it legally anymore...) and it was around $4500 just for that alone.  The guy that does them manipulates the tune on the vehicle to make sure it passes.  The cheaper option is to book into Kangan Batman Tafe (I think that's where it was) and hire their tester.  Allegedly you're not allowed in there with the car though so not in a position to tweak anything to make sure the vehicle passes.  I'm sure in this day and age of ultra tuneable ECU's you could get the tuner to program a special efficiency (clean) tune that emits the lowest amount of particulates possible that would pass the test.  It might only make 50kW's but as long as it passed who cares!

      I'm sure he has left signs, or, he is looking down, laughing That's my cunning plan for when I leave, lots of half finished projects, with no rhyme or reason of where I was actually up to, just to keep everyone on their toes
