Well after much soul searching andmany years I am going over to the darkside!!!
As some of you will know although the rally car is a 33 all the running gear is Sud.
After a worrying off on Epynt last year caused by a broken splined section on an outer CV I am going to go outboard brakes. Breaking a driveshaft is one thing but losing all the brakes i can assure you is no fun at all.

I can understand that in a rally car. TBH I can understand that in any form of competition :D I don't think in your case the increase in unsprung weight will make a whole lot of difference to the performance, and as you say, you do have that extra peace of mind. Easier to cool too, so hopefully less fade?

Going over to the dark side could have been much worse - I thought you were going to announce you were moving to a non-Alfa :lol:

I guess you've a bit of time to make the conversion before your next scheduled event???

Although it does involve replacing all of the front suspension I'm hoping once it's done I'll be in a better position for the future. Sud stuff is getting harder to find. For a while I'm hoping 33 will be easier. To keep the same size brakes outboard I've only found one sty!e of alloy that I can use but luckily John at justsuds had 6 so I snapped them up.
Going to try and do something with the top mount and reinforce where the strut sits as well
GAZ have said they will do some struts so only got to sort out mounting the discs and calipers.
If I say it quick it sounds simple!

I went with inboard brakes so many years to keep the unsprung weight as low as possible.
But as the engine was getting stronger, the car faster and the brakinge distances longer, I decided for the conversion to outboard brakes on my sprint as well..
I hope, i can test it this year someday, somewhere..

That looks like a nice conversion. What size discs did you go for?

Disc size is 304 x 25,4 mm. Rim size ist 8x15. Choice of good race tyres and traction is much better with 15"

Very impressive.
Did you go with 16v hubs or the earlier type?
What are all the numbers on the disc bell?

Hubs and drive shafts are from Alfa 33 S1 (905).
Numbers on the bells are measurements for the floating mount of rotor and bell with special bobbins

Any
Particular reason you went for the early type as I'm told spares are getting hard to find for them?

Do you mind me asking how much lower and torque your brakes will be having to deal with?

No particular reason. There were several drive shafts and hubs in my shelf. It was no prpblem to get new wheel bearings.
What do you mean with how much lower?
Torque of the brakes? Depends on disc size and brake pads you use. I went for Tarox rotors, as they never disappointed me before. And the AP Racing calipers should do the job as well. Not cheap, but good value

My mistake.
I meant to say engine power and torque

That looked awesome.
Only one problem I noticed.

Steering wheel is on the wrong side!
