I'm not sure if it has RX-7 springs or GLC springs in front. It does have RX-7 strut tubes, stut cartridges, and RX-7 front brakes, I believe. Also, the tops of the struts have four studs and the strut towers had three holes. I've seen pictures of RX-2s and 3s with RX-7 strut assemblies before, so it's not an uncommon swap. I don't know what the best way to proceed in raising the front end, at least by a little, because I don't have access to the original struts, and I don't know suspensions very well. The car was like this when I got it (engineless).



When there is no engine in the car, the front end is up at stock height. With an engine, it looks slammed. The struts or something up front is obviously vastly shorter than it ought to be. I don't know if this is a good thing or not.



I need to raise the front end some how. If I have to build some 2" spacers or brackets to raise the car to a respectable level, it's hopefully not beyond my meager abilities. Wishful thinking. What I have in mind is something kind of like the opposite of the Racing Beat lowering kit where instead of raising the upper mounting point to lower the car, it will lower the mounting point to raise the car. I'm sure some aftermarket springs like Racing Beat or Eibach (if Eibach is still available) wouldn't hurt.



Man, I really don't know what I'm doing when it comes to suspension. Where's heretic when you need him?



As for your rearend, it would be nice to get it, but I have no money at this time. I'm not sure when I'll get any for this project. I'll let you know as soon as I know. Hopefully within two weeks.

GLC13B

I have a website somewhere around here that has after market suspension parts for are types of car's. I believe there in UK and i'm going to have to search for it. I really don't know how much more the 3rotor weight compared to a 13B but my car is still perky from the front. I also believe that the springs from the GLC are taller than a rx spring. What year rx suspension do you have in the GLC ? Are the brake's bigger than the stock GLC brake's ?

Also, You pay for the shipping and it's your's ! You can square me away later !

The 20B supposedly weighs 75 to 80 pounds more than a typical 13B from the same era. That would mean S5 and 13B-RE. I lightened mine by removing the stock heavy turbos (62lbs) and waterpump. I replaced them with a 21lbs header with most of its weight at the rear of the engine and behind, and an S4 NA waterpump at only 9lbs. The extra length of the engine (160mm) went rearward only. It also got a Racing Beat light steel flywheel.



Compared to the 13B that I briefly had in the car, the 20B weighs only about 40lbs more because the 13B was all set up to go into my REPU, including the stock 30+ lbs flywheel and cast iron waterpump along with heavy (early) rotors and all that jazz. I'm going to relocate the battery to the rear hatch area and having recently weighed a typical group size 24 battery and finding it to weigh a little over 40lbs, there is a chance the 20B will break even in weight over the front wheels now that the battery (another group size 24) has been removed. It's still 40lbs more than an S5 or 13B-RE, but 40 is better than 75 or 80.



I'm hoping some suspension work will make the front end feel lighter and mask the extra weight. That sure would be great.



The front springs must have sagged or something because it's awfully soft in front. They're definitely stock springs. Aftermarket wouldn't be that wussy. The extra weight is of course part of the problem because it feels tightly sprung with no engine in the bay. That's the sort of suspension stiffness I'd like with an engine in there. That's how my REPUs are. Man, I wish I knew all the details of my car's swap because it would make this a lot easier.



I think the front disc brakes are from a '79 SA22C. They are vented if I remember correctly. Did '79 have vented rotors? The calipers are different from REPU/RX-4 etc, which I'm more familier with, but the pads are the same.



You're willing the let your rearend go just for the cost of shipping? Or would I still owe you something later? I'm confused.

I've got rx7 struts on the front of mine now, with coilover tubes and 12" long 180lb springs I can raise the car above standard ride height and drop it to somewhere sensible.



For a good deal of info on what I have done check out http://www.mazdarotaryclub.com/forums/show...4767#post154767



I believe the company who do parts for 323;s are whiteline and they are based in Aus ... theres some other place that does uprated springs too (peddars?!)



Got to sort the brakes and test drive it now

It looks like I need to be a member of that site.

Jeff, If you need the diff then it's your's ! You have help me many time's before so, in return you need something and i have it, then it's your's ! When you're ready for the diff just PM me.

Jeff20B

That is really cool! I have a couple engines to rebuild and one to install and get running for my brother before I can get back to the GLC. I'll let you know when I'm ready. Shouldn't take more time than, oh uh... weather permitting, maybe a few weeks? Or maybe sooner. Can you hang on to it for a few weeks?

GLC13B

That shouldn't be a problem ! I'm taking the car to the Chassy shop in about two to three weeks from now, so then i'll let you know it's off. I'm going to leave the stock brackets and all the other little things from the GLC that you'll need to place it right in like a stock differential.



Hey, By any chance you know the number or e-mail adderess to Whiteline suspension ?

Jeff20B

That will be very helpful. Thank you.



Sorry, I've never heard of Whiteline suspension.
