I don't know if it's a problem with AW11s, but AE92s (which have the same powertrain) have floppy and fragile engine mounts that would do well to be replaced with solid material.
I got mine modified with solid rubber pucks in place of the original material. Vibrates quite a bit near idle, but they'd be on the luxurious side for a dedicated race car.
The front engine mount is the one that transmits everything into the cabin. I found that going solid on the sides and rear and putting a new OEM front one doesn't really make any more noise than stock and tightens everything up nicely.
For engine R&R, I drop the engine to the ground on a plastic tote lid, then bolt a chain to the rear tow hooks and put my flip flops between the chain and rear bumper and send the chassis skyward. You can easily slide the engine out the side on the tote lid and it won't even crack the paint on the rear bumper. I've pulled an AW11 engine and transmission in <2hr by myself with only hand tools. You can unbolt the front an rear engine mount brackets from the chassis, if they don't look rusty. Then you won't have to work around them when dropping the engine.
For endurance racing, I always put stair tread grip tape on the driver floorboard. It makes driver ingress, egress a lot easier and decreases injury risk...especially if it's raining.
Brake bias in these cars is kinda wonky. They really like to lock the FR wheel first. Not sure how best to approach it, but something to be aware of.
I would also lose those silicone cooling hoses. Those thing love to get cut, abraided, or blow off. Especially with worm drive clamps. I like the stock corbin clamps, if you run across a parts car.
You guys rock!
Edit: Swapping the radiators and fuel pumps on these cars is a blood letting. I wouldn't want to do it trackside. I also fabbed an in-line water box with a temp sender and an Chicago-style air fitting. I use a Pressurized bug sprayer with a corresponding quick-connect and ball valve to pressure bleed the cooling system. Connect it to the pressurized water bottle (>12psi or whatever the rad cap bypass is,) throw the valve, when water comes out the overflow then it's full and bled. Cooling system can be tricky to bleed and this comes in really handy if you're losing a little water anywhere at a race.
Edit2: I like to run these cars with a little bit of negative rake, unless you have roll center adjusters. Firmer in the front and more compliant in the rear. Zero toe up front, 1/16" toe-in in the rear, whatever negative camber you can get, or about -2'.
