Deleting the sunroof

Welding & bonding in the existing sunroof panel is by far the most cost effective method of delete if you're unconcerned that externally it still appears the car does have a sunroof. No parts cost, very little labour (far less welding) and no filler. I guess it comes down to your reasons aesthetics/function. The costs for the other options involving the purchase of an infill panel don't end there. They require far more labour to fit. I mulled over these options for a while (new skin was never on the cards) and eventually opted to weld & bond in the existing panel.

The weight is in the 'cassette' and mechanism, all of which is removed, with only the panel itself put back in

Cut the whole roof and replace it with a new roof

>what are the weight savings?
When I did this in this thread here
...it came out as
"The sunroof panel itself weights 5.1kg and the waste material 7.6kg (excluding the thin metal internal retracting cover)"
So all in its about 8kg saving from the highest point on the car. The stock sunroof panel is double skinned so could be picked apart to drop a bit more. I wish I'd gone that bit further with it.
I did the mod primarily to increase cabin headroom for when you have a crash-hat on and secondly for weight.

I carried out a sunroof delete for a customer earlier this year using a Fenn lane panel, it worked out well.
Pictures here if it helps anyone.

Guys,
Have heard that welding in a panel, such as the Fenn Lane item often results in cracked welds later on as the rood twists under normal use and track work. Anyone know anyhting about this? I know replacing the whole rood is the best option but it is just too expensive.

No cracking, although the filler did shrink back slightly so the trained eye can see a line, which bothers me.
My chap used a http://www.u-pol.co.uk/product-cat/85/body-fillers.htm filler. Unsure which one but he was particular about it to avoid cracking.

I have done 13k spirited miles since fitting the panel, including chasing you around Spa.
