will 5 114.3 fit my 95 gs300? the back riim is 20x10 20x9.5

 

try to find out what offsets they are.

 

I have 19x9's and it just clears the front of the wheel well with no rub and my car is lowered alot. 20x9.5 will likely rub. your offset is important too otherwise the inside of wheels may hit the suspension componets mine just misses the suspension but my off-sets are unique.... I think my front's were 47 and rears were 50. I'm reworking my suspension and alignments as well as modifing the wheel wells for a perfect fit and alignment. This was unavoidable since I dropped the car and using coilovers. It changed my toe and camber signficantly.
