Weight Distribution Query

[TobyLaRohne]

Hi guys, I'm preparing for a race coming up and I was wondering if I could ask for some of the more knowledgeable sorts on here to test my logic for me.

I have an EP3 Honda Civic Touring Car I'm preparing for my first propper race.

The minimum weight for me in the series is 1100kg for the car and driver (without fuel).

I weighed the car and the results can be seen below. My query to you lot is, where is the additional 40kg best being located?

Option 1) Passenger seat location (as shown) to try balance the L/R weight distribution of the car
Option 2) Stick it in the rear to help increase the weight over the rear wheels?



Currently I dont have enough experience with the car to be able to tell how it handles on the limit. All I'm looking for is a logical place to start given my limited degree of experience.

Thanks for your consideration.

Where you've suggested, on the passenger side, is fine. You may want to move it a little more forwards to pop a bit more weight on the FL, but basically that's fine for starters. If you want to be exact I'd suggest making sure any other fairly heavy items, like the fire extinguisher, are in the same area as the ballast.

Ballast in the passenger seat location would be the best solution and is the default choice for most of us in the club racing paddock if you check over a few other cars.

You need to add 40kg!, ah yes I forgot how heavy Spencer was (well he is over 6 foot and not slight of frame, sorry Spencer).

As stated put the extinguisher in the passenger area as well as the ballast.

cheers for the advice chaps, its appreciated! I'll have the weight as far to the edge of the car as possible to maximise its effect.

I wouldn't put it towards the outer edge, as that will affect the polar moment of inertia, which will be more detrimental to performance than a 15g cornerweight discrepancy. Passenger footwell should be fine.
