Yes. This is LUGGING the engine. In fact, this is lugging the engine really bad, so that the power strokes don't have the power to accelerate the engine, which basically causes detonation to occur. VERY bad for pistons and rods. You don't have to get that awful shudder for it to be bad for the engine either. Anytime you're stepping on the gas and the car can't accelerate you're straining the engine. It's time to downshift.

I've had my Paulsen steel circle track wheels balanced at the local tire store and never had a problem with vibrations FWIW.

That is a damn fine idea Drax, so I just went out to the garage and made that change. I was thinking it might be easier to work on my sway bar end links with the thing on the rotisserie, so I figured what the hell and went for it. I also welded on the engine stand pivot. I'm pretty comfortable with the way it is now. Thanks for the input everyone. Pics...

Here's my reason why you shouldn't: your head! Search and you'll find many arguments for and against cages in street driven Z's. I'm generally opposed to the cage. Roll bar fine, cage not good.

Yes I am 99.9999% that the Hyperco will have the same problem everyone else has. Spring rate is based on the size of the wire and the number of coils, and you don't have too much room to play around when you already have the ID and length set. Check with Ross to for the extra .0001%.

If it's perfectly straight why have a joint at all??? I suppose it makes driveshaft removal easier, but from a strength perspective you might as well have a torque tube setup...

Yes, because an 8" spring will coil bind before the strut runs out of travel.

I'm sure you're right Jeromio. I thought he was saying the area where I was going to jack the thing up was strong enough (mine isn't going to have bottle jacks on it), but now I see that it was supposed to be bumper mounts. I think from everyones' comments it will be OK the way it is, but it was the side load on those thin bumper attachment areas that I was concerned with...

Read this thread on why you SHOULDN'T get a 200 lb 8 spring on a Z... http://forums.hybridz.org/showthread.php?t=102442 Maybe you could get some extra long bumpstops?

Mine's not going to be a pumper at all. Just some modded engine stands here, nothing fancy. The body will be stripped. Kinda funny about the 280 bumper shock comment. Those tubes in the picture are actually brake ducts I added a few years back.

The fronts are exactly the same. The rears have a 1" taller spacer. The damping is exactly the same according to John Coffey, who got that from Tokico.

I have a question for those who have gone before me. Is this an OK way to mount the 240 front end to the rotisserie? I don't see any other real easy way to do it, and I looked at a BUNCH of rotisserie threads and couldn't see this issue dealt with specifically. It's a pretty thin section of sheet metal there, which is why I'm concerned a bit. There is a brace behind it, but is it enough??? What do you say?

Sounds like a good workaround. As long as the gland nut doesn't bottom before it tightens you're fine. The struts are all the same as far as damping, just the spacer on the back is different and the front number is different just for customers' sake. Somebody evidently made a mistake at Tokico with yours, but your solution will be fine.

Fugly.

Why not just cut it out for clearance around the camber plate and then weld the part onto the the strut tower? I'm pretty sure everything else bolts to the strut tower piece.

Seems like it would be harder to work on a car on one of those lifts than it would be to just put it on jackstands. Those two long ramps would be in the way if you were trying to do anything more than pull drivetrain stuff. Basically anything that wasn't right in the middle of the underside of the car would be tough to get at. That's my 1st impression. If memory serves Jeromio has a lift like that. You might want to ask him directly.

I have a cheapo 20 gallon oilless compressor that a friend gave me. I've moved it from house to house 5 times now, which is why I haven't ponied up for a 60 or 80 gallon 220V one yet. I don't know the duty cycle on mine, but I just run the compressor all the freakin time, and it's held up to my 8 years or so of serious abuse. I'm not worried about breaking it in the slightest. If it did I'd go buy a bigger one. If you eventually want to go big on the compressor, you might think about getting a cheapo unit to fill the gap. I simply couldn't have done many of the projects that my little crappy compressor has gotten me through, so IMO something is much better than nothing. Mine still has a price tag of $180. I'd say it's definitely paid for itself.

There's been lots of discussion of the Tokico springs. Search for that info. The rear struts are taller than the fronts, and the rears will have a spacer under them where the fronts do not. The problem with J's struts is he got the ones for a 280Z. The 280Z has a 1" taller spacer than a 240Z, approx 2" for a 240 and 3" for a 280. The struts are identical even though they have different part numbers, so that isn't a problem. What does worry me about that situation is that it sounds like he cut the spacer so that the gland nut bottomed out. It's not supposed to bottom out, and when the nut is fully tightened there should be a couple threads visible. Simple fix if he cut too much is to put a washer under the strut to space it up a bit until the nut fits correctly.

I think a fairly easy test would be to check the diameter of the strut tubes with a caliper. The 280 tubes have a larger diameter, and if it has the 280 tubes then it HAS to have the 280 chassis. Bumpers and the rest could still be screwy, but that will at least tell you what the chassis is.

Just cheaper. Search about the TC rod bushings. Use Afshin's name in your search. Interesting bit about ZX's and the rod bushings about a year and a half ago...

Call them. They have lots of stuff not listed in the catalog or the website.

That don't make no sense. CV's don't have U-joints.

The guy with the 750,000 lived in San Luis Obispo and drove back and forth from LA to SF so his was almost exclusively Highway 101 miles FWIW. Still, 750,000 and the head had never been off the block.
