Traded the 3rd gen for a 4th gen

Fitting 16” wheels on a 4gt

So Ian’s some 16” TRD Baja wheels from my 3gt and decided to try and fit them on my 4gt before I got new 17’s and 37’s. After a quick attempt to test fit I saw there was going to be a lot needed to get these to fit. Was it worth it, nah not really but I wanted to try. First off the front calipers are much bigger up front compared to 3gt and older gen Toyotas so the tapered barrel of the TRD Baja wheels hit the caliper before I could even seat the wheels on the hub. I decided that since there was so much messy casting on the calipers I’d just grind it off. After grinding quite a bit of cast marks off I decided that was far enough into the caliper I didn’t want to damage the integrity since there’s lotta pressure going thru them. The wheels allllmost fit but the taper was too drastic that I ended up having to install some 1.5” spacers on which made them clear by a few mm’s. And since they poked so far out at that point I had to do a decent bit of trimming at front and back of the wheel well/arch. Was fun for awhile but I recently swapped them out to my current setup of 17’s and 37’s hope this helped a few of you hoping to install 16’s.

Had the 3rd gen for about 5 years planned on keeping it for the long run but once the 4th gen’s came out I just had to get one, so I traded the 3rd in for the 4th. So far pretty much everything better in my opinion, looks better, seats feel better, the “cockpit” feels nicer and more beefy I guess you can say, no gear hunting compares to the 3rd gen, way easier to fit bigger tires, the list goes on, so far I’ve put over 25k miles and no regrets so far! Here’s from day one to about day 10
