Should Sedan Min weight Be Lowered?

I run an Xray T2 w/ Lipo and BL, to get my car properly balanced from left to right I had to add approx. 130g to the outside of the Lipo, race ready my car weighs 1492g, so even if the weight rules were reduced I would still have to run my car at 1492g to get the proper balance.

Also...I would not recommend hanging a LiPo off the side of your chassis unprotected...reasons are quite obvious.
Keep in mind, moving many batteries even 3mm can cause issues with wires interfering with top decks, bulkheads, belts, ect.

Minimun Weight Should Be Eliminated!!!!
Delete that $&%#*@ing Wieght restriction yesterday already! All of the advantages of a lighter car needs to be developed/exploited/finetuned/dialedin, ect, ad nausieum so the Hobby/Sport can evolve and or grow, and the process needs to start now. Race classes are already devided by motor size, and thats all the restrictions necessary. Any added weight beyond what is required to balance the car is waste of hardware. Maybe a heavyer car suits your preferances, then so be it. As for me, I say, put the lightest car you can tune and drive on the track, and let the games begin.
Hey Verndog, mind if I call you "JulesVerndog"?

5-cell is also faster because of the lower weight... Also less wheel spin, more useable power as opposed to the stupid winds (what with 6T brushed motors)...

I have examples of people with Mi3s last year who drilled their bulkheads in order to try and lose weight. This year the reaction by the BRCA has been to increase the minimum weight from 1350g to 1425g where EFRA only went to 1400g, only because the Mi3 is so heavy...

I advise against changing the weight minimum. All racing has weight minimums for a reason. Perhaps when Nimh batteries are no longer being legalized for racing we can begin looking int changing the weight minimums. The voltages of the batteries are equivalent, so should the weight requirements.
Watching how many cars dropped out of the mod qualifiers/mains at the nationals this year would tell any thinking person that the minimums should not be lowered. Everyone knows that the MFGs would take advantage of those lowered requirements and make lighter weight parts that are more brittle/weaker. You only need a few clean runs to win a championship, and the chassis only has to last that long - we don't need that mentality in the design ranks of RC.

I said this before last years Reedy race.....we as driver's are too stupid to motor down and be in control of our cars. We run killer cells (IB's at that time) and the hairy horse power (6T &7T) and then complain about it. Oh well.....that's they way the ball bounces.

Even when we ran 05 and T-2 X-Ray's with NIHM and brushed systems and(rubber tires) we had too add weight to be race legal. Now with brushless and lipo we add more weight. My vote would be to reduce the weight for everyone. With 5 cell Mod it's 51.8 in the Florida State Series. I would like to see Touring Car (rubber tires) go to 51.0 across the board. ( just my 0.2 worth ).

Maybe my suggestion of using 3200's would be a little low for some racers, but I think some point the capacity has to limit out. But IMO 3200's are ideal since remember mod racing used to be run on 1500 NiCds. Just like any other racing, "fuel" management is part of racing. Going to a excessively large capacity removes that aspect of racing.
I for one don't like standing at a drivers stand for 30min like in nitro. If I did I would be a nitro "blockhead". Why increase the cost for racers in buying bigger LiPO's packs when the extra capacity is not being used except to balance out a chassis that was designed for heavy NIMH's. 3200's can be bought for roughly $50 less a pack than 5000's.
Reducing the total mass of the car will reduce the strain on drivetrain, the load on motors and batteries,the wear on tires, and the damage in wrecks.
Yes it would be unfair for NIMH drivers, but the lower min weight would be more fair than making a LiPO only rule. If the progession towards a lower weight does not start now, more problems will arise in the future.
When racing goes completely LiPO only, the min weight change can be a drastic change over night. I suggest taking small steps now in lowering the min weight so that larger problems are avioded.
