Vespa ET3 Tuning

Hi guys,

Small introduction here. I'm Sil and I have the history of building the fastest dutch vespa ciao. Now I'm a little older and currently in progress for my motor driving license I would like to buy a Vespa ET3 and tune it.

Before tuning I would like to enhance the handling, by replacing the suspension and introducing disc brakes.

So maybe you guys could get me started a bit here.

Am I right that it is possible to fit this steering column with this brake kit? Any of you have any experience with this? Of course I will also order a mounting kit. Which rims and tyres do you guys recommend? Should be also the proper ones after tuning (30+ HP).

Question about the suspension; I'm thinking of replacing it by the lowered Bitubo suspension kit. 

To be sure, I also need the shock absorber base plate? And what about this speedometer cable, is it also required in combination with the SIP speedometer?

Hope to hear from you guys, because I'm buzzing to get started!

greets from chilly Holland

Well,


I did more research myself and I have found a lot of answers but there also raised a lot of new questions.


What do I need to mount the 20mm disc brake kit to an ET3. Do the items below with the SIP steering column fit? Or do I need more? Can somebody help me with this?
