We have not measured the specs from the Meisters. They're O disk with 3.5" front lips on front and O disk on rear with 4.5" lips. We used 55mm and 40mm spacers to get them somewhat fit.
Front fenders are 50mm and rears are 80mm.
My new wheels are 18x10.5j -22 and 18x12.5j -35.
Those should poke out around 20mm on rear, fronts should be pretty flush on the fender with 40mm extendet lca's.
Yellow Equips were 18x12 -24 and 18x13.5 -16.
Those specs should give you some idea what you need for this wide fenders / flares.
Ps; If you have custom aluminium dash pictures, send me a PM or give me some pictures in here. I'm thinking of ditching the OEM dash and going "full retard".
I've been doing some small thing with the Soarer, I've not had time for the S13 lately. When winter comes, me and my dad will get our hands back to the Bunny and try to finish it for 2019.
If you have any questions about the bodykit, wheels or any of the mods I've done, I'm happy to give you some help if you want!
