Based on this scaling below - what would driver experience on front wheel drive car - road racing;

LF 850. RF 608

LR 422. RR 545

Weight in lbs.

Also what wear characteristics would you see on car ?

More understeer in right turns, more oversteer in left turns. Better trail braking potential (will tend to lock inner rear) and power application on left turns.

Less than optimal straight line acc'n and braking as best grip is achieved with equally loaded tyres across the axles.

You can pull some of that cross weight out by adjusting the spring platforms, if you don't have easily adjustable platforms you may be able to spacers under or on top (preferred as sprung mass) of the springs or even adjust the ARB's (sway bars) linkages to pre-load them.

You may also be able to move the battery, and other heavy components, to better balance the loads by moving the CoG. If you're a little 'heavy', losing weight will also help.

Would this setup also cause issues with overheating brakes and cook front LF bearings ?

My thoughts, and it's a good idea to get as many opinions and feedback as possible - anyone else?

I would expect the overheating brakes to be a simple problem of expecting them to do too much work for what they are.

If you're having a problem with a spongy pedal, a higher boiling point fluid, and regular bleeding, should halp. If you're having a problem with a hard pedal and reduced braking force, you may benefit from a brake pad material that has a higher operating temperature. However, if the brake disks are getting hot enough even that won't help and you're going to need to look at bigger brakes and/or better cooling.

Some ABS systems can apply differing brake pressure as grip allows, this may cause the LF to run hotter - but I can't comment in your case. Something that may cause overheating of the bearings is the use of an OEM disc assembly that is one piece with the nub, or even a two piece design where the disc is fixed directly the the hub - these allow a much more direct heat path from the disc to the bearings, and may be part of the problem - another good reason for fitting a high performance disk that uses a separate hat to bolt to the hub as they can drastically reduce bearing temperatures.

Racer D, one of the most pronounced effects I would expect to see that I didn't see brought up in this thread so far would be worse inside front locking coming into right side corners.
