JZ Machtech Upgrade
- Thread starter andcop
- Start date
I have both and the result is great. My dampers needed doing anyway as I understand most do after 40k miles or so and I've had the kit for about 12 years. Its not too hard in normal driving but much more positive when pressing on a bit.
The ECU is less noticable but when I had it done the dyno showed my car was down on power and JZM traced most of hte loss to a simple problem with the throttle (only opening to 80%). The combination of that and the ECU really did make a difference!

p.s. the other decent thing about the suspension setup is that its not stupidly low - my 993 gets over bumps/dips that hit a 996 chin spoiler every time.

I had the Roock suspension kit done by JZ a while ago, very good esp when the original ones were shot anyway and the transformation is truely amazing! The car was actually more comfortable even though it's meant to be harder than the standard set up. On limit handling is sharp and predictable.
I later had the Monoball solid shock mount installed as well which sharpened the steering no ends, although you get a fair bit more road noise.
I beleive they stopped doing the Roock kit, and started using the Manthay ones now.

Thanks for the information. I have booked my car in to be done!
Out of interest did anyone change the stabiliser bars?
The originals are 20mm Front and 18mm Rear.
The MO30 bars are 22mm and 20mm respectively with the turbo bars 1mm bigger at the rear?
Not sure what this would do and if for normal sport driving this would make a noticable difference?

I can confirm all comments. I also had the JZ suspension upgrade but with upgraded MO30 roll bars which I think really improve grip. RS bars were much more expensive, mainly because they are adjustable, which I would probably never use. Very pleased with whole set up and car handles much better with acceptable ride height and not too hard. Strongly recommended.

H&R are available from the continent at 26mm front, 24mm rear. Price is reasonable at about £260 per set, although would they be a bit too extreme at those diameters?
