Chassis Lower Edge
G13BLocost - 13/6/19 at 07:29 PM

Good Evening,

Has anyone ever failed on their chassis lower edge radius? The only way I can think of passing this on my car (square tube chassis) is by putting some form of edge trim along the lower corner of the chassis.

Interested in knowing peoples solutions.

Cheers,
Josh

Normally the panelling is wrapped round the side of the chassis and riveted from below so you can't even see the chassis

Aaaah but in Locosts there is no normal!

I have riveted my panels to the side of the chassis which means they finish is a tidy 90deg angle at the bottom. Looks great, IVA nightmare.

Caterhams have the same lower edge, and they pass, as have had hundreds of Locosts over the years,

As the lower edge is only 100mm of the ground, I cant really see what can go under one of our cars except rats and kittens

When i IVA'd my MNR, MNR provided an IVA friendly kit which included lengths of wood angle trim to go along the bottom edge of the bodywork. I mustn't have fastened them on very well as the fell off very soon after the test

Not a Locost, but my MK Indy GRP side panels returned under the lower chassis rails so they weren't exposed. SVA and not IVA at the time, but I don't recall the tester paying any attention to this specific area of the car during the examination either.

To overcome what you describe I'd have thought some rubber tadpole trim strip glued or riveted along the underside with the round edge along the outer edge of the chassis should solve it.

Do the edge solutions have to be glued/permanent fitting ? My car has a front splitter with a sharp edge and the wheelarches.

Is that rubberised U channel edge suitable for an iva pass?

Good question! From a lot of reading it seems people get away with super glue.

Yes if it is stuck on, you can get self adhesive "U" edging as around the Poly in this photo Description

or the type with moulded in clips is OK.
