After reading it seems the best options are b6 front shocks with eibach springs ior good quality coilovers like gaz golds and input to this would be great as I'm currently on b4 front legs with apex springs and gaz gold rears and want to take track days a little more serious thanks

What size torsion bars are you running on the back?

Ive had bad experience with GAZ coilovers on my 205.

As peter eludes to its all about the rear with these cars. Not beacuse sorting the rear is anything special or unique but just beacause of the TB design its easy to neglect doing.

 

I found when I first started doing trackdays the cheapest way for great balance was a 24/25mm rear arb. Cheap and easy to install. Combined with as you mention B6 fronts and some suitable springs. Bear in mind if you go down the b6 route you have no scope for adjustment. Coilovers will allow you to play around with spring rates to get something you like.

The rear is just a rebuilt 1.9 beam

I'd start with at least 21mm torsion bars. ARB after that. Until you do that there's no point spending money on the front. I ran revalved Konis and reset GTi springs for years.

306/xsara arb will need cutting and welding/resplining

saxo/106 disc beam arb fits but needs a spacer to make it stay central so is an easier/cheaper option [need 306 endplates tho]

You can buy thicker arb's and tb's off the shelf for 205 beams. Not sure of the quality or best place to buy but plenty do them

I'm about to buy some new parts as follows; 25mm rear ARB & 23mm torsion bars...

in terms of balance with the rear going this stiff, will going up from 17mm to 22mm on the front ARB be okay?

No! I would suggest at least 275lb front springs.

Most if not all bar's come from performance torsion who sell direct, But there are a few posts on here about it and going from a mate running 21mm bar's we are not convinced by the sizing

 

Damper wise on a budget I;d go the Group N route, otherwise it starts getting expensive.

Have emailed them for a comparison quote, will let you know prices, we're using PTS struts...

Front arb standard thickness, fitting bigger one doesn't help.

We will see then...

 

Torsion Performance are quoting:

£220.00 for 23mm torsion bars and £110.00 for rear 25mm ARB - considerable savings when looking at Spoox prices, although the latter claim their material spec is the same as original PTS.

That is quite a saving deffo worth a try at £330

Spoox used to supply torsion for performance bars as far as I'm aware

All you need to do is ask if they're heat treated. That sorts out the pretenders from the real suppliers.

I think thats where the difference In price comes.

 

not sure how much it would cost to heat treat the cheaper bars as the quality of the machining is good enough.

Down under, it's the same as the machining costs.

Spoke with the boys at Torsion Performance who say they don't heat treat their torsion bars and have never had any problems, reasons given were the process can cause cracking? In respect, they couldn't tell me too much to protect their business, understandable, I'm not a mechanical engineer so I don't fully understand why there is a requirement to heat treat torsion bars?

 

I do though understand the price difference between £220.00 bars and £375.00 bars, I need your mechanical advice/knowledge, thanks!

Did they snap Henry?

 

 

If I ever get mine finished I need to get a 28mm arb and was looking at torsion performance.
