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!

Hi there , I have a 765 and wanted to go with Toyo Tyres which I have a set already , rear would be the 315/30/20 which fits as standard on oem wheels , the front is my deciding factor , I want to go 265/30/19 , which fit on oem wheel but rub on the inside , I tested my Cupra 11 mm front spacers with oem wheel/tyre combination and there’s now I think enough clearance on the inside ( not tested on road as I have not mounted the Toyos yet ) , do you know if with any of your spacer combinations this Toyo Tyres would work , regards Nigel .
