Scared about my tyres!
 

I've fit my 195/50/15 wheels on (ET38) to my 1.1 flat arch saxo with 25mm spacers, with no rubbing at the front, even on full lock - but the rear wheels strike a problem.

The spacers would give enough room between the arch and the wheel, but the wheel is still rubbing on the torsion bar, on the inside.

Can I rectify this by putting another smaller spacer on top of my existing one?
thanks
