suppose it depends on the thickness of the polycarb too
barron reccons all his are lighter, but tbh i prefer funtionality of glass front windows tbh
Ours are only 3 mm think so are alot lighter than the glass.
but they are noisey and have alot of flex in them at high speed.
Ott for a road car imo.
Will get alot of track use mate!!
Bazzon, I would get em from there too but can only do 4mm :S
We only bought the rear one from there, our doors and rear quater ones were made for us by a "friend of a friend" as such.
Hence why ours are 3mm and not 4mm, we also have a coating on to help reduce scratches.
if you get fronts, they will scratch in no time being wound up and down, but then if you have sliders they are noisy and some designs like to leak lol
lucky our car isnt really on the road a great deal, but the sliders would annoy the hell out of me.
And to make it worse on hot days you cook in our car no way of keeping cool
Personally if you are planning on doing it to you 197 kev, follow the R26Rs lead,
id do the 3 rear ones but not the fronts.
