What's wrong with TIG?
That TIG welding cannot be the reason. Almost all of the T45 roll cages are and are advised to weld with the TIG. The welding itself can be the reason if itīs made by the person who cannot weld. Maybe the problem is related to roll cage homologation?!
I think this is why.
Article 261 - SPECIFIC REGULATIONS FOR CARS IN GROUP R5
Side 15

Only parts authorised by the present regulations and/or parts mentioned in the “modifications /
lightening of the body” VO may be removed.
TIG type welds are prohibited for the body shell and roll cage.

That's interesting, thanks. I wonder why. I'm no technologist but I do remember that TIG and MIG main difference is that MIG uses meltable metal electrode while TIG uses tungsten one which doesn't add any material to the weld. I thought TIG was preferred for thin material welding but it's a long time I learned about that at school...
Skoda have been testing the Fabia R5 on icy tarmac in the Czech Republic the last two days.
little bit off-topic, but once I was discussing about roll-cages with Prodrive engineer and he showed me some tests they made. They find out strength was same with MIG and TIG welding and MIG was simply cheaper and quicker, so all their FIA homologated cages they were making with MIG.
Maybe also in case of R5 it's becuse of costs?
Could be an explanation. Dziekuje.

Maybe I am talking bullshit, but I have the impression this car is geared quite long but has a super-torquey engine, which is similar to the winning recipe of the Fabia S2000 (relatively speaking).
The car rockets up that twisty uphill section barely using any revs.
You are fully right. According to my info the standard gearbox of Fabia R5 has much longer gears than other R5 and the engine torque curve is very very good.
This kind of makes it sound 'lazy' but it looks fast.
We can look forward to seeing what Lappi can do in Finland then :)
