McLaren Spacers - Testing & Development

As with anything testing and practise makes perfect and along the way for sure there's been some lessons learnt with designing spacers for the McLaren!

For one, a 13mm spacer does not work with a 235/35/19 tyre albeit an oversized tyre for the 600LT (opposed to the standard 225/35). So I will need to order a set of Pirelli Trofeo R's to perform further testing on the front to which I'm also now re-thinking could be better served by an 11.5mm spacer anyhow... This would then roughly match the track of a 235 tyre (225 tyre +11.5mm) which on testing I've found much better on turn in and grip.

On a positive a 13mm spacer fits perfectly on the rear, and given the anticipated track usage the decision to go with the slightly smaller 13mm spacer as opposed to the larger 15mm one I designed means a little more clearance for those hard corners and compressions.

For me 235/35 tyres front (10mm wider than standard) and a 13mm spacer at the rear seems like the best balance for the 600LT and addresses the 'tuck in' from factory especially at the rear!
