Personally I think wheelspacers are wrong, here in aus they are illegal and for good reason, they can come loose, and put extra load on you wheel studs. Offset rims are a good cheap way to get around things, but if you run multiple sets of rubber can become expensive. They also add load to your wheel studs. For me, I run two sets of rubber, 35'' and 32'' and dont wont either rubbing so I installed a 60 series rear diff, 70mm wider than stock, s0 35mm per side. NO extra stud or bearing load and easy mod. HEAPS of room for big tyres now. For the front I used a IFS hub kit. This one
Axle Widening Kit
You use stock hilux IFS hubs and it all bolts up without a fuss and the spacer is used to position the disc back to its original position. 66mm total extra width and no extra wheel stud load, with a wheel bearing load the same as on a hilux. Very happy with the setup and car feels much more stable.
