I was rencently discussing with another RL member whether it is a good idea to use the front tie down points that Rennline sells for the 981 chassis. Obviously there are several benefits to using these, but our conversation turned to the question whether the front jackpoints on the GT4 chassis are designed to be able to handle the specific loads that would be generated by tying down to the RL prices (which are anchored to the forward side jackpoints on the 981 chassis). I believe that the jackpoints on the chassis itself are made in aluminum and not steel (the Rennline pieces are steel). Obviously the jackpoints were designed to handle the weight of the car when lifted from below, but it is not obvious that these parts of the chassis are designed to handle the side loads that one would assume are present when introducing the Rennline pieces and tightening down the ratchet straps to those pieces. Presumably all of the forces acting on the RL pieces are transmitted to the jackponts on the chassis.

Anyone have any thoughts?

Aren’t you referring to the side jack points under the rockers? Those are the locations where the Rennline front tie down parts connect. That is what I was asked about.

this is the same location the Rennline tie down points connect, so if there is any issue with that part of the chassis not being able to take the forces, it would also be an issue with the J hook setup. Separately, I am not a fan of the J hook setup. If you hit a bump and one of the J hooks falls out, you will be SOL. At least the Rennline parts allow you to hook in with a snap hook that has a keeper.
