More progress completed yesterday. Firstly car was dropped on Tein Springs. The Ark dual grip exhaust was fitted but not without major issues. Be careful if you buy one to fit on the Mark 2 Nismo, The tailpipes sit deep into the rear valance and cannot be seen and don't align. I took the decision to have the pipes cut, a sleeve put in the rear section to extend it and have it welded. The final result is fine but its an added cost.
The second challenge was the 25mm spacers do not work on the car if dropped on the Teins. The rears rub instantly. I removed the spacers completely and all the wheelS now sit flush.
Few photos of the exhaust when first fitted so you can see the issue. Have added a photo of how she now looks. Will post some better photos when the sun comes out to play.
