General:
The Aston heavily relies on a lot of rake to generate downforce and to get the rear to rotate. Additionally it has similar suspension issues as the Ferrari and simply cannot dissipate the energy properly, which makes a few parts on any track quite tricky. However, I seem to have found a middle ground where the front end will occasionally bite and the car will behave predictably around the lap. The car does not need a lot of steering input, the chances that you overdrive the front are very high. Race trim should be better for the Aston than Quali in general. Tire wear is not very much and it will pay off the longer the stint goes. Let me know how you like it!

Electronics:
TC1 on 1-2 is enough, but TC1 on 0 might be faster. Any TC cut really hurts but even TC on 1 allows quite a bit of slip before engaging.
ABS should be on 2 at least - rather be safe (3) than sorry in the hairpin! 
Changing BB can make sense. Lower - like 60.8% - helps into the tight corners, but higher, until about 62% will help slow the car down in the hard braking zones.

Laguna:
It's a tricky track in general. It's narrow and additionally has narrow kerbs. The narrower the track, the more every millimeter counts. we only have slow and medium speed turns, while medium already ask for all the downforce. Luckily the aston needs a lot of rake for slow speed corners too, so there's no compromise to make. Though, since we have to aim for so much rotation, the car is slightly sensitive with initial throttle in some turns, however this gives you options to play with the rear on exit, rather than being a victim of your entry. 

Adjustments:

• reduce front bump stop range if braking into corners is an issue, or stiffen front spring. This will also help with bottoming but will ultimately be a little slower
• move BB forward if too loose into the corners, more front ARB could also help here (yet it will make slow corners too understeery imo)
• race setup might be able to run more negative rear toe still. I find it balanced currently, but I'm sure it would be faster maxing this setting out. Just gets quite edgy to drive and more error prone
• There is a direct trade off between rotation and traction. If you add rake, you will lose traction. If you increase rear spring stiffness, you will lose traction. You always will have to counter any adjustments with another adjustment elsewhere.

Driving:

• Basically all turns need careful trailing, but you can still push the higher speed corners - the car tolerates a lot of yaw (if you can get it to rotate, mainly using the brake)
• The initial steering input and response is very important to get right as the car will gravitate towards understeer mid turn
• The earlier you can apply throttle the better, in several corners the car is on the verge of producing power so hit power before you actually need it - and mean it!
• the turbo takes some time to spin up, but when it does you have a lot of power available. This makes the throttle pedal non linear and gives quite some delay with actual engine output. You need to predict this and plan it into the driving. I.e. quite early throttle for the power to be there on exit
• bumps are tough on the car, raise ride height if unbearable (2mm rear for every 1mm front, if rear tops out, reduce wing), but the bottoming should be limited here
• aim for late apex in hairpins, try to trail deep, immediate throttle [+management], no coasting
• shifting at 6800-6900 here pretty much. Do not go over, the engine shuts off!
• it can happen that if your minimum speed becomes too slow the chosen gear stops working for too low rpm. Try to stick to the higher gear and keep the speed up than being forced to shift down.
• In turn 4 you can either stay on track or use the sand on exit. The sand slows you down, but you will carry more speed initially and it seems to just equal out

LFM:
The race setup is dialed in for medium fuel. For full tank lower rear ride height in 1mm steps to your liking. Other options are to reduce rear rollbar, or increasing front, or simply reducing the negative toe on the rear and go closer or directly towards positive toe.
