Ideal COG

[ChristopherK]

I have my car close to built. I set it up for a COG at .75 in front back axel. Now, I’m getting cold feet and wonder if should just adjust the COG to 1 inch. Here are details.
• brand new metal track
• don’t know height of drop or length of track
• going to bend back axels to 2.5
• going to lift a wheel
• going to bend DFW to 1.5
• will tune car to veer 4” over 4 feet
Thoughts on leaving COG at .75 or just adjusting to 1 inch?

Leave it

I keep "hearing" about cars with COG's under 1" getting unstable and jumping off the track, etc. Is that a legitimate concern?

The worst problem you have here is getting your rears tuned right...without a track its a crap shoot...

Better really check those bent rears. The weight is fine.

I agree with Chuck and Troy.....check those rear axles and get them aligned the best you can. I ran bent rears for years. I would use a speed square and cantilevered weight off the side to adjust them individually. Make sure to keep the nose the same height as the dfw is or it won't work well. Look up Stan Pope's alignment method. That's where I got that from.
