Thanks everybody...!

Steering power comes from a Fiat has been adapted to the original steering column, it works very well and the control over the car is always good, especially al low speed because of the slick tyres very hard to move and because the steering gear is demultiplied.

I have two set of tyres: 8x13 ET10 Fondmetal rims with 200-540 Pirelli slick tyres and standard brakes or 8x15 ET10 rims (Rota BM8 to be bought soon) with larger front disks

Here's a pic of power steering
