peps New Member 18 Member For: 9y 10m 21d Posted 30/05/17 08:25 AM Share Posted 30/05/17 08:25 AM Hey im going to purchase some rims in the next few days - was thinking to go with Koya SF01 with custom offsets. FG UTE with tray back. Stock Height on front- rear is on airbag+leaf spring settup. Fronts: 18 x 9 +25 offset (with 255/40 R18 Nitto Invo) Rears: 18 x 11 +35 offset (with 295/35 R18 Nitto Invo) My Question are: Any reviews on Koya SF01 Semi forged Will the fronts fit without scrubbing the internal guards/control arm. If I need to roll my guards im happy, I just don't want inner scrubbing. Rears: _____TRAY_______] |<--175--><--115--> |_______П |¯¯¯¯¯¯¯Џ<-Hub | |<--less 30mm clearance from body of ute and airbag will 30mm clearance be enough to clear once the tires are mounted to the rim. Hopefully my diagram works, if not ill draw something up soon. Thanks guys. Link to comment Share on other sites More sharing options...

peps New Member 18 Member For: 9y 10m 21d Posted 30/05/17 09:16 AM Author Share Posted 30/05/17 09:16 AM Any idea of the offset? I currently have 275/35 r 19 mounted on a 9.5 rim. It sits about 10mm in from the tray. But the wheels came with the car so I don't know the offset- backspace is 165mm. Link to comment Share on other sites More sharing options...

peps New Member 18 Member For: 9y 10m 21d Posted 30/05/17 09:21 AM Author Share Posted 30/05/17 09:21 AM isn't offset distance from center, backspace distance from outside lip of rim? Link to comment Share on other sites More sharing options...

peps New Member 18 Member For: 9y 10m 21d Posted 30/05/17 09:25 AM Author Share Posted 30/05/17 09:25 AM yeah, as I don't know the lip size I didn't think it would be an accurate conversion. I threw it into an Backspace > Offset calculator with 12.7mm Lip and came with 31.65 Offset. Link to comment Share on other sites More sharing options...

It's crude but gives you a good idea on how it'll all line up with respect to the guards/suspension etc. Link to comment Share on other sites More sharing options...
