Hi Frank,
no problem, please always feel free to ask as we've had a bit to do with RF1 as well in fact it was all current production until recently. At 8 degrees of front caster you are likely to see some increased steering effort and given the steering arm is not removeable ie one piece with the upright you will start running into some additional bump steer unless you alter (raise) the rack location. There will be diminishing gains, probably around 8 degrees. On an Aus built RF1 you could achieve your desired 8 degrees within the std pick up bracket using spacers.
I'll look forward to an email, always happy to help and from Huw's last PM it sounds like it has improved a lot over the last week which is a nice result so far.
Hi Jim,
I am having a close look at LHD at present, everything on CAD is finished (to match the characteristics achieved on the local cars) and once the actual rack arrives and we set it up I'll let you know. The change to the front end is quite substantial and includes steering wheel hub, column, intermediate shaft, rack, upper and lower wishbones, new uprights and associated hardware, hubs, rotors, shock mounts and springs. One of the design constraints we set ourselves was to leave the chasssis pick up points per RF1 so that these retro fits will be achieveable, we are nearly done on the local RHD retro fits, the first builds have had the changes for some time. Thanks for your interest, we'll keep you posted,
Regards Paul
