That's exactly why,
New build will see around 350hp on max boost and would like to use as much of that as possible on track.
On 195s ATM and tbf they handle 280hp very well.
Must admit would be interesting to find out if they have the moulds for 15x8 or wider. May not be very light but certainly a cheaper alternative. I have been looking around for wider wheels without dumb offsets for my track mx5 but so far can only find the 6ULs but they are quite pricey and difficult to source. Every other 8j+ I find wheel is like et20-0
