Does anyone have any photos of ballast attachment from their cars?
I've read the GCR and understand the rule, I want to see some visual references.
Thanks.

300lbs of lead in 100lb blocks. Yup. ITR S2000.

Damn that's a lot of lead. And a lot of trust in those nuts and washers.Quote:

Since I'm going to STL , I can move my weight to a better location than the ITA specified location. My current plates no longer fit in the new location , so I need 160# ... I priced out 10"x12"x1/2" plate from
www.metalplatesource.com
With shipping it was almost $ 400.00

Go on eBay and do a search for "lead". There are numerous sellers that ship lead using USPS' "if it fits it ships - up to 50#" boxes for $12-$14. So many different forms available, including sheet.Quote:

This is how I did it on the Integra; there's another piece of steel plate underneath the body panel backing that up.
Other than location, I think it meets the intent of the IT regs.

Greg, exactly what I was planning except one bolt in the center of the weight, and one outside the weight.
i prefer steel over lead. i had borrowed some lead from a friend and had trouble keeping the bolts tight.
the lead is so soft it kept deforming enough to have the bolts loosen.
the difference in CG is minimal.
one thing i did to help secure the weights (i had three 50#) was to weld in brackets in front and behind that the weights sat in. this helped from a fore-aft load and helped line-up where to put the weights. i was installing/removing depending on if i was running Honda Challenge or ITB.
If you have a space problem, you could always use spent uranium. :rolleyes:Chuck
I mount 1 5#er, under the car as a washer. Bigass all thread through the weights. Double nut both ends.
