hi guys ive just fitted some 5mm wheel spacers on all 4 wheels, took it out for a spin and it drives like sh1t. the steering wheel shakes like crazy on uneven roads, and when i pulled out to overtake it felt like i was gonna lose the back end :( (but it drives ok on flat roads its as though every bump is been exajorated) could it be that the car just needs re-tracking, or could i have bought sh1te spacers. as anyone had similar probs with spacers? cheers si

My zed just passed its MOT today with flyin colours i am chuffed to bits i can finally start spendin some money on it i think a bodykit and some wheels will be first on the list WOO HOO..... :bow:

Hi guys, although the summers over, im thinking my zed would benefit from a bit of extra air flowing under the bonnet, and was thinking of getting vented bonnet (maybe CF?) for my zed. Ive had a bit of a look around and not really found anything too tasteful (ie dont want max power / evo style huge vent!) Im more after just a couple of vents (one either side) that dont over power but let some air in. Was also thinking as ive got a black zed a carbon fiber bonnet might look nice, particularly if i paint most of the bonnet and only leave a bit of the CF showing. Anyone seen anything like im describing above?

both good and bad. Found a major leak in the seal for the metal pipe that connects to the plenum on the underside just behind the drivers side throttle body. One of the bolts was loose. It was a PITA to do but now thats tight and sealed. Sorted. Found another leak..... Its coming from a rubber pipe about 2 inches long right at the back of the engine, passenger side under what I think is called the AIV valve near the battery....... how the fook do you get to that :rant: Need to get that sorted asap. I still can't pressurise the system very high, maybe only 2 - 3 psi (crap guage). Anyway, took for a spin after sorting the first one and I'm still only gettin…

How can i check it and change it? Can i just open it?

You were heading Guildford to London, I the other way. Didn't spot you till quite late. This was on Sat about 1100. Nice looking Z.

Right, i took the car out earlier and filled it up with fuel, after this its felt fine, no missfiring. Ive just been out with my dad (so he can check it too) and it was fine on the drive revving it. We took it down the road and it was all good until i went round a corner and it started to missfire, then it ran smooth again. It missfired abit more every now and then but not as much as in the past few days where it missfired all the time. Could it be the fuel filter? If so where is it?

put cats back on stopped it smoking at @"£$%^& last, two years now !!!!!!!!!!!! i was just about to have the tubs done ideal :dance:

My zed seems to have gotten audible gearbox wise. Nothing major, but you can certainly hear it inside the cockpit with the t-tops on. Only in 2nd and 4th. Is it the bearings on that shaft that are on their way out or is it a lube related issue? Still changes fine, not crunching.

whats the best stuff to protect under your car ,mine looks mint and want to keep it like it.

Has any1 fitted decat pipes supplied from petrolheads northwest? The hole pattern at the turbo end seems good to bolt straight onto the precats, but the angle out would make the pipes stick out and drag along the floor! Do the precats need removing and a separate elbow from the turbo to the decat pipe need to be fitted? Thanks, Joel.

I have the infamous seat of my pants vibration for the first few miles when cold... Ususally spells centre support bearing, but could also be gearbox mounting or U/J also. Is there a way i can acurately diagnose the cause....?

As some of you know I've just finished an auto to manual conversion, now its all completed, I have a bit of a problem engaging ALL gears. Thing is, if I drive the car slowly I have no problems at all, no grinding and engaging any gear is fine. But if you try to give it a bit of a right foot it will grind into all gears, even 5th. I've bled the system twice and there is no air there, tried adjusting the clutch pedal, still no luck. Some one suggested that pressure plate might be a bit weak, I know that the friction plate was changed very recently. What else could it be? bent fork. The car I got the g/box from suffered a heavy front end collission, but visually the g/box …

Hi, I found out last week that the 300zx came with t-top storage protectors. How do they work? I know there are some straps in the boot, so I assume they are used to secure the t-tops down? Is it worth buying the covers? Any for sale?

What's that all about then ? I'v seen it mentioned quite a lot What are the advantages/disadvatages ? Easy to do ? Do you have to remove the plenum or can it be done in situ ? CheerZ Paul
