I've searched the forums and found good info but hoping to sanity check my plan before pulling the trigger. I've a stock 72 240Z 4-lug that in time I will want to upgrade to a big brake kit, probably the one from Arizona Z Car or others. I have an immediate need to put new tires on the car but don't want to throw my money away. My plan: Buy 16's/17's rims with +25 offset and use a 4-lug to 5-lug bolt-on 25mm converter/spacer to allow them to fit. Probably XXR531s. Looking at a tire size of 235/40/17 or slightly smaller if possible in a 16. When I do the brake upgrade, the AZC kit moves the offset +19mm, I drop the convertor/spacer and use a thin 6mm or less spacer on the wheels. This way I'm thinking that I can buy the new rims and tyres now, and then the only thing I'm throwing away or selling at the time of the brake kit upgrade is the convertor/spacer. I do not plan to run flares, but from my research this set up should fit flush or within the stock fenders. I'm fine with trimming front valance if necessary and worst case rolling the fenders also. I plan to run coilovers at some point and drop the car only enough to make it look right. Thoughts from anyone that has been there and done that GREATLY appreciated.
