First of all hello! i am new here, having used the site however for many months as a non member!
I was wondering if anybody can clear up the issue of how much lower the standard GSI is than other astras?
I have read that it was 20mm lower front and rear, but have also read it was ONLY lowered 20mm at the front aswell!?
With my GSi it does appear that on a flat surface the front is lower than the rear! My brother has a 1998 mk4 astra 1.4 with 17" on aswell, i measured the arch gap at the rear and it was the same as my GSi! The front of my car is 10mm lower than his however. Hus suspension is totally standaed and we have the same brand of tyres with similar tread depth.
From what i have seen i am swayed with the opinion that the GSi was only lowered at the front but would like this clearing up! lol
