there are 3 types of fitment... with this kit....
The: stick on and paint, Running spacers
The: bracket, bond and smooth on, welding fuel filler cap extensions etc, leaving as much inner arch as possible... Running Deep dish alloys
The: Complete removal of inner wings + ABOVE + widening the track
COMPLETE removal of the inner wings is a LOT of work and is very unsuitable for a modified road car... Extensive work needs doing.. strengthening, etc..
+ track widening
.... Spacers are fine to run on the car aslong as they are suitable, I ran 32mm RE-BOLT aluminium spacers untill i got my 14x9 et15 wheels...
Widening the track is ideal but not worth the investment unless you were prepairing for 'rough terrain' time..... OR want to run sill 18'' rims..
Lowered + hard suspension + small wide wheels for tarmac use... is what I prepped and modified my car for...
Still a major investment in time and money either way... My wheels are only suitable for Wide arched cars, they wont fit on a normal micra....
Please note that despite my wheels being et15 14x9'' I dont foul the inner front wings when on full lock...
