Rear Chassis Brace Install- Pictures

Ok there's been many posts about the need for the lotus track use chasis brace kit, but not many photo's. The merits (or lack there of) have been discussed at length but I thought I'd post some photos from my install of the original lotus kit part number - LOTAC05377. I bought the kit from South Bay Lotus right after the WCLM track day where Marcw's stock toe link bolt failed, the price was $835.58, ouch! I had the rear of the car appart to install my new Larini exhaust so access was easy. Nothing to hard about the install other than the usual trouble of trying to decipher the Queen's English instructions. I now know what a "subframe plinth" is though. It's tough being a ruffian from the continent intrusted with the care of this beautiful machine. All I need now is a rear end alignment and I'm ready to roll. One more thing here's the tourque specs converted as well, 50NM = 36.88 ft/lbs, and 45NM = 33.19 ft/lbs. Hope you find the photo's helpful:


1) The Full Kit (minus the new sperical joints) Loosely assembled off the car
















2) New Sperical Joint attached to toe link




3) Cross Brace Mounting Point on Bottom of Engine Mount (the mythical subframe plinth)




4) Right Hand Side Loosely Assembled




5) Left Hand Side Loosely Assembled





6) Crossbrace Mounting Point loosely fit (i.e. finger tight not torqued yet)





7) Full Deal Before Being Torqued Down

Carl helped me with this installation on Sunday, and here are a couple of things we learned.

I echo Don's suggestion to use longer bolts (see red arrow in attached photo). 25mm should be about right.

My car is an early one (chassis #334) and the cutouts for the engine mount bolts are much smaller (and rectangular). Note in the other photo the red area, which was solid on my car (for both). It took some grinding to open that up to be able to slide in the nut.

So my recommendation is to get a couple of longer bolts and have a heft grinder available BEFORE you start this project.

There's a turnbuckle (circled adjustment) at each end of the crossbrace. It allows you to adjust the length of the crossbrace so everything lines up. since the crossbrace is attached to the frame at four points, once at each rod end and twice at the middle to the motor mount, I think Lotus wanted to insure that everything lined up properly. Manufacturing tollerances being what the are a little extra adjustment is a good thing.
