Is anyone running Rpf1s with +35 offset on the rear of their SW20?

Is so would it be possible to measure your wheel track for me, from centre of each tyre?

I am considering an upgrade due to issues with my current wheels and tyres but because I need an engineering cert and pits inspection I cannot go more than 26mm over factory wheel track and in theory as original factory rims are +45 offset I should be ok but my current rims are supposed to be +45 and my wheel track is already 10mm over factory
