hey,
yes it is an Invidia exhaust.
The car is build up to the group N reglement
The tire size are 18" because it's not allowed to drive larger wheels in german races so we decided to try the stock wheels first and it works well.
the suspension is a KW competition 3-way coilover system which setup on their own 7-post drive dynamics test stand. it's so amazing to drive this car with this coilover system
now we will develop together with our tuner ctd-germany some parts and tweaks for the z. more information soon.
best regards thomas
