Aerodynamic

It'll be an interesting comparison having the same rack/powerplant in two cars from totally different eras. I remember stumbling across that retrorides thread a few years ago and getting the idea in my head. It gives good idea of the work involved to make it all fit. Thanks again and looking forward to more progress!

You're welcome, that sounds like a good balance you're striving for. I also agree with your sentiment that serviceability is important, especially with Z parts getting harder to find (at reasonable prices at least lol). I've been super torn weighing the pros and cons of whether to incorporate a power rack into my own build plan. Right now I'm leaning slightly towards keeping my manual rack.... I'm not sure how hard of a decision it was for you, but your crossmember design is pretty inspiring. What swayed you most in the end?

Been following your build for a little while and I just wanted to say excellent job on your continued progress. I have a wrecked 2005 M3 and have been planning this swap myself for some time. Out of curiosity, what are your plans/goals for the use of the car? Will it be a more track focused machine (chassis reinforcement, minimal interior)? Purely a street car? Or of course, a mixture of the two! Thanks

Hey sorry for the slow reply. Didn't get notified that anyone replied. Since I have Koni struts, I went with Koni's own bump stop. Part number 70.34.95.000.0 I agree with you. Some of those poly bump stops aren't any different than not having bump stops at all.

So I checked over the suspension and yes, there are definitely needle bearings in the top hats below the camber plates. I have bearings for the springs on order so I'll see if they help. Yes sir, I was talking about those. I realize now those bearings aren't actually dealing with rotation of the shock body directly. I'm going to be heading to the alignment shop again soon, as I have installed some adjustment in the rear I would like to dial in. I'll ask them to take a look at the fronts again once I install the bearings and new bump stops.

Thanks for the replies. This just happens on the left side. The right side seems to have no wear whatsoever, and the spring and strut tube turn together smoothly. I'll double check if they came with bearings in the hats. I know that the gold blocks in the T3 camber plates have bearings built in. So in short, I need those bearing top hats in addition to the bearings already in the camber tops? The coilovers came pre-assembled from T3 before the install. I'll have to check if they had the hats with bearings, if not I'll definitely be getting a set. Funny that it would happen only on one side...

Hi everyone, I was wondering if anyone could help me with a problem concerning my left front coilover. I have new T3 coilovers on the car along with camber plates that I installed relatively recently. I have maybe driven ~200 miles since the install, however I have noticed when turning left at low speeds (such as backing out of a parking spot), the spring and perch will bind causing a really loud "pop" noise. Please see linked video. Apologies if the size is large, I couldn't figure out how to change it. As you can see by the sharpie mark I made, the perch does not turn smoothly. It seems to bind and then pop with the spring into place. The popping noise is fairly loud and makes me look like a terrible owner haha 😭. I then jacked the car up and noticed that the spring is rubbing and has shaved off part of the threaded section. This is probably what is causing it to get stuck: I guess the spring is somehow misaligned between the upper and lower perches, but it seemed odd as the spring was properly seated on the lower perch when the car was loaded. I dropped the strut assembly and checked for straight alignment (which it looked perfectly fine), bolted it back in, and put sharpie on the threads to see if it would still rub. It still rubs!!! Anyone have any suggestions on what to do next? The popping and now the visible rub is making me not want to drive the car

Found what I was looking for. Thanks everyone. Moderators, I wish to close this thread.

Hi, first post here! My 1974 Datsun 260Z... I am daily driving it now, but I want to put more serious work into it!
