Alloy optional parts on the SV2 result

[dirk702]

I would like to know what the result if I use the optional "U3929 Alloy Yokes 7.5 Deg" in combination with "U3934 Hub Carrier; Zero Trail Alloy" on the new Cougar SV2 ?
Does it makes the wheel base more longer ?
And it have to be used under what track conditions ?
