FYI: the stock silver springs are 10 lbs.

We have some new items on our web site. It is a set of burgundy (same as the limited edition cars) anodized bulkheads. P/N WH18110 is all the bulkheads. WH18111 is all the bulkheads plus the toe in blocks at both ends of the chassis. This is a great way to "tune up" a car if you have any bent bulkheads or if you have an E4JS or E4JR it is a great upgrade over the plastic bulkheads. Of course the real reason for this is that it makes the car look awesome!! The kits cost less than the price of 2 plain bulkheads. These are in stock and ready to ship but are limited supply.
