Can someone confirm what the stock ballast is for the 07 Supra 21V? I think it is 650 front and 2x400 rear but want to make sure.

Looking to upgrade for next year and want to know what I have exactly...

Your sacs should have a label like this on one end. The last 6 #'s are the dimensions in inches. So this bag is a 10x16x70 and wieghs 400 lbs. What size are yours?

Thanks for the info...

My backs are 101670 and the front is 161670 so it does look like I have approximately 1450 lbs.

I know about putting the center bag in the back and buying another center bag for the back and putting in a larger center bag. But I'm happy with the wakeboarding wake and just want to improve the wakesurf wake.

I'm already going to buy a Fat Brick to balance things in the boat when it is just me and the kids. What do you guy recommed I buy to use when we wakesurf if I want to keep my stock bags? Buying a couple Fat Bricks has crossed my mind and would let me move them when we switch from Goofy to Regular side. Me and the kids are all Goofy but we have friends who aren't.

Or is it better to just bite the bullet and replace all the stock bags?

I bought one 20x20x50 750 lb fat sac with the quick connect fittings so when we want to surf I just swap out the 400 with the 750 on the surf side.

I've never heard of a 16x16x70 bag. You sure that's right? Your ski locker must be quite a bit deeper than mine because by 10" tall bag barely fits when full.

That front should be 650..
I was under the impression that stock 21V was 1450 (650 /400 / 400)
I wish I had a 650 in mine!

I think some folks put an even bigger one in there...

Yup I'm pretty sure the front one was 161670. From calculating the volume compared to the 101670 that does work out pretty close to 650 and 400 for the rear. I still have more room for a longer taller bag in the front locker. Would more weight up front help wake surfing as well?

Getting a 750 that you switch out as needed sounds interesting. Does the 750 bag stay within your rear locker or does it extend out to under the front seats. I'm not sure how much taller I can go under the front seats.

My understanding is the 06 21V had less then 1450 and I wasn't sure when they made the switch to 1450.

I don't know how I am going to get through the winter. As a first time boat owner, we bought the boat 2 months ago, I am missing it badly.

The 750 fits entirely within the rear storage locker on my boat.

Won't need more in the center locker for surfing.. you'll need more in corner..
