Looking to the guys who know. 50/50 Weight Distribution the Best?

Robert that car is going to be a head turning sleeper! Very impressed with the build.

My 1800 from back in the day.............

Lady I sold it to totaled it three weeks later.

I am running 265/35/18in B.F.Goodrich G-Force tires in the rear, so I am thinking I will need to do something to help with the grip in this case, and that might be strategic weight placement.. I didnt want to mini tub, so I cant get the 12in wide rims in that little body, but I think it is a pretty large tire by proportion for this car..

I know you'd love more tech advice but I've just got to say that I love the car! What a great off-beat project! It looks great and I love the sheet metal fab work you've done! 538hp in a 2700 lb car is going to be quick!

Good Luck!

here was a thread from a couple months ago on the subject. Getting beyond 50/50 with more rear bias is pretty hard with a front engine car, but the implication is to get as much rear as you can without biasing by hanging weight behind the rear axle - creates a different issue.

I couldn't recall the thread but searched for the Aventador I recalled mentioning

I didn't realize you had that much, so yes, try for more rear bias. You are going to need rear traction & the rear weight will help.

With 265 rear, what tire width are you running on the front? IMO, 50/50 weight distribution needs to be accompanied by relatively balanced front to rear tire widths too if you are looking for the easiest way to get midcorner 'neutral.' Although, once you accelerate on corner exit with 538hp, that 'neutral' will quickly go to 'oversteer' and you're going to need to take care of the throttle or perhaps dial in some steady-state understeer (via more rear weight, and/or tire) if you want to be more aggressive coming out.

For sure, driving style will play a big role in how neutral the car feels.

Rear bias is good with that hp level BUT also keep in mind that as you brake, turn, accel, all of those wieght numbers change to.As it will when you have fuel level changes and driver, pass weight changes.Weight disturbtion is also dependent on use of vehicle. A car set up for drag racing will not handleas well on the road or in the twistys.Stan

PS you are talking static weight but keep in mind dynamic changes.

I am running a 18x8 front, with a 235/35/18 tire, so and I think that works about to be about a 1.5 inch overall footprint difference, but I would have to look that up.

With this setup, I am actually looking for the best of Daily Driving/Road Course fun, or atleast easy set up for each, by being able to easily add or remove weight if necessary. I will be daily driving this car, and I would like to be able to drive it to what ever event, and the just hit the track within minutes.

In a front engine car you will never be able to obtain too much rear weight bias. I'd be impressed if you even made it to 50/50. Bottom line, move everything to the center and low as you can.

Judging by the preliminary numbers, I am going to be right at 50/50 (Front 51.7% Rear 48.3%) initially, and I will have the luxury of adding a bit of strategicly placed weight.. Most of the weight I have to add now, will be in the center of the car.
