What wheels are you going to use? 8" wide beauties like on the original Autodelta Trofeo's? Might need some wheel arch extensions!

Luv ya work Michael! Both wicked looking cars!

How have you gone about attatching the bottom mounts on the front end braces? The 16V rails seems to have a special mount fabricated there where the crossmember fits up?

hi, very nice car
here's my tuppence worth on the poly bushes. I see you have them in the panhard rod. I would definitely not fit them there in a sud, not because of the increased sideways stiffness, but because of the increase in torsional stiffness. Because of the watts linkage type arms the axle pivots whenever the suspension moves up and down and this movement is taken up by flexing in the panhard rod rubber bushes. If you stiffen them up the twisting is transferred to the panhard rod itself and also the mount on the chassis leg, one of which will eventually break. I would use rose joints.

just read your spec for the engine when you do it and wanted to say, dec the block NOT the heads, if the heads are done it alters the shape of the combustion chamber and wont increase squish therefore the piston comes up the block further.

Fly33Boxer,

On your silver Sud I see you have some strengthening bars (in red) between the bulkhead and the chassis rails, where are these from??

Thanks,

Jaty.

First of all a beautifully prepared car. I only wish all track cars were this well prepared.

I raced a Sud many, many years ago and made the MISTAKE of installing those red poly bushes in the front and rear suspension of my car ... it went from being exciting on the track at 11/10th's to EXTREMELY exciting and while single lap times did not suffer, over a race long distance they eventually did as the driver tired, etc.

Thus I have circled in yellow the bushes that MUST be removed and rubber returned at the very minimum to allow the front suspension some compliance.

Also you will need to lock wire your rear suspension trailing arm bush bolts as the poly bushes WILL try to undo them ... and then you get a rear wheel steering car, which just adds to unnecessary excitement.

Best
Pete
ps: Oh and learn NOT to lift off the throttle during corners ... unless you want to exit the corner looking out your rear window

Cheers.

Yeah not sure if I actually need them, as the Sud seems to be stronger and better built around the front end than the 33. Also where they attach to the bulkhead it is a hollow section on the Sud so can't just put bolts through the bulkhead without any kind of internal strengthening sleeve, something would need to be done there too.

Think I'll see how it goes before I add them.

Ta.

[fly33boxer]

Oh they need them, if you look closely on most suds/33s they have or would have a hairline crack on the chaissis rail. Just on the underside where the cutout is for the cv when the suspension is fully compressed - common fault.

And i have already sleeved the bulkhead too

Hmmmm....interesting topic this is turning out to be, as opinions seem to be divided Yourself and a few others believe its needed and then I've spoken to some racers over here who believe it is not neccessary!!

I have no cracks where you mention (yet!!) but suppose there is no harm in fitting them.

If I find some, I'll probably fit them..........better get it running again first anyway!!

Cheers.
