Default Kosei K1-TS

I found a set of 17x7 Kosei K1-TS wheels for sale that I want to get for my car. The seller says that the wheels have a +36 offset. According to the tirerack website these wheels are only available in +42 and +50 offset in 5x114.3 bolt pattern. Does anyone know if these are available in +36 offset? They were on a 2004 Infiniti G35 sedan.

What kind of car do you have now? All of those offsets will generally fit most Lexus cars and RX's too... +42 or +50 would be closer to OE fitment than +36 is, but we're talking just over 1/2" difference between +36 and +50 anyways...

I have a 2002 IS300. I know that they will fit but, I need a 45-50 offset to stay legal for autocrossing. The seller measured the backspacing at 5.735", so the 36 offset is correct.

For a 7" wide wheel, I actually think that is closer to +50...

where did the seller measure the wheel from? a 7" wide wheel usually measures around 7.5 or even 7.75" wide due to the width of the rim flange... lets say its 7.5" and the backspacing is as measured is 5.735" which is 190.5mm wide and 145.7mm backspace. Centerline would be at 95mm. Difference between 145 and 95mm is 50 mm, so, 50mm offset. If the wheel actually measures 7.75" wide, which is common for alloy wheels, then we are at 197mm wide. Centerline would be 98.5mm, difference there would then be 48mm...

So, you might be ok and its a seller issue!

I don't think that the seller knows wxactly what he has. I am going to keep looking to make sure I get some with the correct offset. Thanks for the help.
