Most people advise 15mm front and 20mm rear wheel spacers, but when I installed them that way it didn't look right. The rear tyres where proud of the wheel arch and the front tyres still looked too far inside the wheel arch.

So I installed them to opposite way about and now the wheels look the same filling the wheel arches out the same 🤷‍♂️

Good luck with them! They were fitted when I bought my vRS and taking them off was the first job I did. 20mm spacers will throw the Ackermann steering angle out and you'll end up with severe wear to the edges of your front tyres.

P.S. Anyone want a set of spacers and longer bolts? 😄

Had car in today for wheel alignment. No adjustments made, was the car on lower springs when you bought it. When I did lowering springs on my car excessive wear on the inside of front tyres.

Wheel spacers won't alter the wheel alignment when set up in the straight ahead position, it's the Ackerman angle (named after the bloke who came up with the idea) that changes with spacers. The angle is carefully set up in the design phase of a vehicle to change the angle through which the front wheels turn to ensure that the different radii of the circles are compensated for. If the front wheels are spaced out, especially by as much as 20mm, that angle is upset and you will get uneven tyre wear. Simple geometry.

Most modern day cars don't use the Ackermann system but the rack and pinion system which the vRS uses.

The Ackerman angle is nothing to do with the steering system as you put it. It is the angle between the steering arm and the "straight ahead" position of the wheels. The Ackerman angle is calculated by measuring the angle of a line drawn between the vertical between the steering joints and the centre point of the rear axle. Ackerman angles apply irrespective of whether it is recirculating ball, cam & peg or rack and pinion mechanicals. See a better explanation here:

If you put spacers on the front wheel without any adjustment to the steering angles, you WILL get uneven tyre wear and perhaps some very odd handling characteristics. Fitting spacers will move the steering centre outwards with consequent tyre scrub when the wheels are off the straight ahead position. Believe me, I've been there....
