The settings i paid for are different to WRX and STI settings and Subaru WR1 settings, they are specific for the WR1 from Prodrive not the local dealers who tend to use STI settings... They are designed to give the best all round setup with reduced understeer ideal for twisty B-roads. As with all low profile tyres you will get tram-lining on some roads - there is one near me that i get it on but not found any others yet...
To get the most out of laser wheel alignment you should really do this with 4 preferably new tyres if not very evenly worn tyres. Also the tyre should be balanced and tracking checked to ensure the whole geometry is setup correctly. Prodrive also said that these settings were tried and tested on their cars using Pirelli Nero tyres.
It would be interesting to find out from any engineers/physicians out there whether they think a geometry setup would change with different tyres due to the varying tread pattern...
