Aside from the spoler and front bumper tuning, does it matter where I put the rest of the weight on the car?
For example, I want to make my car 2500 lbs. If I have 2 of the exact same car, but one of them has lighter rims and lighter engine parts, and the other car has heavier rims and heavier engine parts, but both equal out to 2500 lbs, does it really matter where the weight goes? Also pretend I’m not concerned about building a handling or top speed car. Just need general advice here.
Thanks.
No but the closer to 50% distribution the easier it will be to tune. You fix the weight distribution via tuning.
It actually can make a difference as rotational mass, (i.e. heavier wheels) is harder to get going and it may be more advantageous to have lighter wheels to get the rotation going faster.
Nope, Acceleration and Aero are king.
A reduction in " rolling weight " free’s up horse power, not by a whole bunch, theres a formula I’m blanking on at the moment ( -30lbs lighter wheels= approx 1.7 - 2.1 h.p I think this is close ) the best you can hope for is 50/50 distribution across the chassis. Mid and rear engined vehicles are a lil tricky-er, when tuning your suspension: small/incrimental increases or decreases- you will find that sweet spot in time, and hopefully not the wall quicker 
Remember grasshopper, balance is the key to catching fly with chopstick. Hope I helped Good luck!!!
you want more weight over the powered tires for more grip. under braking weight naturally shifts to the front that can give you grip to cut into the corner. so it will vary if the car is fwd or rwd
