Hi everyone,

Some history- I was building a 33 race car (only because i couldn't find a sud). luckily enough Ive been that busy that I haven't had time to do much.

Which is good because Ive now come across a 79 sprint in pretty good nick, which I picked up on Saturday and will keep as a road going car. Has fairly fresh 1.5L twin carb, flogged out gearbox and bonus rear disc brakes.
I have replaced gearbox with 1.2 sud box and lsd. When i refitted this gearbox I used the spacers that came from the origional sprint gearbox(see photo) they are 23mm thick. I used them to match up to the 16v suspension I have fitted. Is the correct? Does anyone know if I actually need these spacers?

Any help would be greatly appreciated.



thanks

Hi Kack
I suspect the spacers must relate to the spacing of the strut mounting, tracking and camber angle of the front wheels. IE If the Strut mounting distance Left to Right is the same on a Sprint and a 33 and the front track is the same, and the gearbox drive flange width is the same on the Sud gearbox as the Sprint, without the spacers should be ok. BUT if the 33 track is wider say then the spacers will get the track correct and the camber angle will be right. Hope this makes sense? (But I expect that you will need the spacers!)

I have fitted the spacers and it has given the front wheels massive neg camber. Might try taking them out and re asses the situation

If it looks wrong - then it probably is wrong! So trying without the spacers is a good plan.

A nice Sprint, a 1.2 box and an LSD, you lucky chap

The part you show in the pics is the driveshaft to gearbox spacer for a Sud/Sprint with inboard brakes. It shouldn't have any effect on the suspension or camber angle.
Sud and 33 driveshafts are different. You may need to experiment a bit with different thicknesses to get the end float in the driveshaft correct.
Cheers,

Sudsonic, very tidy sprint indeed

Markp2, I think I might loosen the driveshafts off with the car on the ground with weight on it and see what sort of gap there is.I cant think of any other way of doing it unless some one has done this conversion and knows what size spacer is required or if one is required at all.

mark2p is right, the question is, what driveshafts are you using. The spacers are needed in relationship with the driveshaft lenght, there were 2 kinds of spacers on sud/sprints by the way, this thick one for the original 4 bolt inboard disks, and a half the width one, used with the later style inboard discs, where the driveshaft bolts secured the discs to the flanges.
I'm not 100 % shure, but I think 33 driveshafts dont need any spacers.

 

[kack]

face, I am using the drive shafts from 16v 33, All other suspension pieces as well except for struts, I have S1 33 ones bolted in at the moment as the bearings on the bottom of the spring pan on the 16v ones have come apart.

Cheers

I am sure there are others on here that know more than me but in my opinion, the handling and steering on the earlier sud/sprint with the inboard front brakes is far better and more precise than the latter sprints with the 33-based suspension. I have a later sprint and then had to go buy an earlier one as a result.

PS lovely red sprint by the way!

The correct spacer to use is the thick one if using 16v driveshafts. Car all up and running with new gearbox and modified front brakes

When you replaced the suspension did you use the front and rear trailing arms from the 16v suspension or the Sprint ones. I a number of differnet lenght arms for my sud, and i use the short 33 ones to remove some of the camber, then adjust it further by slotting the struts.

I will check the lenght of the arms in the weekend and post here, this will have a large impact on your camber.

Unfortunately or fortunately , rear trailing arms are not the same and cannot be used to Sud and Sprint plus those from Sud are better due to be thicker....

It is the front ones that I have changed over i think, there was at least an inch worth of differnace in them. what is differnet about the rear ones?.

Problem is that on 33 suspension , all trailing arms are facing at the same direction (at the rear) while in Sprint and Suds they create a square with the long ones facing forward. I discovered that when i tried to fit a 16v axle with disks on my Sprint and of course 33 trailing arms would fit or those from Sprint fitted on the new axle . I had to leave the rear axle as it was and swap just the ends with the disks only.
