OK thank you all for input.
My accumulated suspension bits (so far) are ..ALL.. Mk4 1500 Spitfire sourced.
Was just horrified to discover that my rebuilt Spit rack takes 4.25 turns to crank it from one end to the other.
Also that a reproduction rack of quickened ratio was available for V little coin.
Are these Chinese (where else?) mfg'd reproduction racks of passable quality??
Although the oem triumph racks in my previous Loutii :-) S2 and Europa, both requred replacing as they grew serious wear/slop on their central rack tooth(s)
So clearly, oem Triumph ain't of outstanding quality either IMO:-)
IF I understand it correctly, the Caterham uses TR6 intended Trunnions which feature a Steering stop bolt/stud. Wouldn't removing that bolt seriously decrease the U turn radius? Although I suspect that steering stops are there to 'save' the cycle fenders from fouling the body ?? My old clamshell winged S2 had no such U turn radius issues, easily doing an about face in my Drive. Europa on the other hand was poor at this.
As digression if I might :
I have 'on hand' my pore old Saab 900, which I'd hate to send it to the crusher after 27 years of loyal service.. but?
It features V nice Uprights (actual ball joints, No trunnions :-) , massive ATE Brakes and hub centric design Ronal magnesium alloy wheels, of surprisingly light weight.
Granted these suspension bits ..are.. heavier than the Venerable Triumph one.. but also of 20/25 years more advanced /evolved design.
My question is: is this an inappropriate choice of suspension parts ?
Has anyone tried this before ?
Just trying to explore other possibles.. while I still can
Thank you.
