Fenix I-mola Conversion Kit for WRC
26 June 2013
Fenix in Italy have made a conversion kit for the WRC F-one 180mm F1 chassis. We asked designer Giorgio Favaretto to tell us all about it.
By Giorgio Favaretto
Everything started about 8 months ago, when I got the chance to own a WRC F-One.
I found the car to be best suited to grippier surfaces than your standard every Sunday track. So I started to work to improve the situation.
After collecting feedback from a bunch of fellow drivers the result is a chassis extremely oriented to "Joe Average" , the Sunday driver who needs a car to be very tuneable in a matter of minutes - which is me… ;-)
The carbon kit components:
A converted WRC F-One 180mm:
Rear suspension has been completely re-engineered, moving toward a semi-rigid link. This version of links allows a very reactive movement "t-bar like", plus we’ve worked in order to get a different rigidity.
While working on the rear side of the car, we wanted to improve the traction, especially on "green" tracks, so we come up with a "fast" solution to tune up the rear.
The wheelbase can be adjusted within a 7mm range, in a matter of 5 screws. The shock location on the upper deck has the same 7mm step, so no need to adjust the pre-load of the shock spring.
Clearly, being an upgrade kit, we wanted to retain as much as possible from the original WRC F-One kit.
So far, the front of the car is pretty much standard WRC but… we found the chance to be able to play with the wheelbase also on the front side, very intriguing, so we end up with another 5mm adjustment.
Changing the wheelbase on the front has a dramatic effect on the steering capability of the car, especially when entering the turn, with a different behaviour than a short wheelbase.
I-Mola has 4 wheelbase options: from 254mm to to 266mm.
We’ve had the huge opportunity to have WRC driver Matteo Berlincioni racing the I-mola at the very recent Austrian ETS
Matteo was in the top ten for 4 qualifying session, in the last one his Cirtix ESC blew after 8 laps forcing him to retire.
Despite the B main, we are more than happy with the results, the car has shown immediately a good level of performance.
On the technical side, the kit is made using 2mm quasi-isotropic carbon fiber, using waterjet technology (my company is called Fenix Waterjet, see it at www.fenixwaterjet.com), while the whole package has been 3D drawn using Solid Edge, all the testing was carried out using Ride R1 tyres, which are very popular here.
We’ve a "closed" group on Facebook
And an active website www.fenix-racing.com
The plan is to start from this point and make F1 oriented parts.
Thanks Giorgio and good luck with your venture.
