306 Torsion Bars And Brakes With 266 Mm Discs

[Guest hassan]

i have already rear 306 s16 suspension and i want to use its components such as torsion bars after shortening and its brakes components to convert my GR drum brake to 266 mm discs.............any body can inform me if it is possible?

No, you can't shortern the torsion bars (atleast without cutting and re-welding them) as they aren't thick enough to re-cut the spline.

 

You can shortern and respline the anti-roll bar though to fit a 205 beam, as at 24mm thick there's enough metal to recut the splines - if there's someone in Egypt who's able to do that sort of work - or cutting and welding one end straight to the ARB endplate.

 

The 266mm front brake setup will bolt straight onto any 205 except those with 1.6 GTi hubs

i want to fit the 248 mm rear discs of the 306 s16 on my rear beam is it possible anthony?..........

i mean by shortening the tb's to cut the end then respline the end in the size to fit to the 205 rear beams .. i dont believe in cutting and welding... do you think anthony that i can kill my problem when somebody in rear seat cause the rear wheels to hit the rear arches in rand small bumbes although my car isnt too low rideheight at back.

I thought all 306 discs were the same as 205 ones?

 

No you can't just cut the torsion bars because they are to thin to put splines on, they get wider at the end and you will be cutting this bit off.

 

Are you using stadnard wheels and tyres? Has the beam been rebuilt as these could both have soemthing to do with rubbing.

That's easy enough - either use the complete trailing arm assembly from the S16 beam with your 205 torsion bars and tube, or you can transfer the parts that are different across - hub/bearing, stub axle, caliper mount, brake lines and of course the caliper and disk

306 rear disk setups are indeed the same as 205 ones, but his will be drum if it's a GR beam mentioned in the first post.

many thanks Anthony..

my wheels is 185/60 R 14 .. i think its one of the standard sizes.. but the problem of rear wheel hiting rear arches makes me use the car as a 2 seater one and my family hitting me every day we go with the car as the smell the tyre.

Do you think that cutting and welding it to the endplate will last ?, my project involves a 24mm ARB from a ZX16V that i´ll cut down to fit my 309beam. I´m thinking a lot about how to connect the cut down end to an endplate, one idea was to make a cutout in the axle for a key and having a keyed connection to the endplate.

 

But... you think it might hold up to weld that end to the endplate ?, i´m not shure....have been thinking about it though, it shurely is an "easy" solution.

There are companies in the UK that do cut and weld and it seems to work from what I've seen - I much prefer the solution that 205Parts employ of cutting the bar to length and re-spline the ARB which then fits as standard (which is what I have fitted on my car), but I don't know whether any engineering firms are able to do that near you, or whether it's cost effective posting an ARB to and from the UK... I suspect not on the later atleast.

Of course i meant a coutout in the ARB for a key in my post above :-)...., not the axle, just as a clearification.

Are 306 torsion bars the same length as 405 torsion bars?

i dont think so as there is differance in wheel track between them.
