IamScotticus Posted March 28, 2022 Posted March 28, 2022 (edited) On the Matt Lewis site, and possibly elsewhere, is a line of differentials, the BlackLine, which appear to be very similar to the QUAIFE torque biasing diffs. These run a few hundred cheaper than the Quaifes. Does anyone have experience with these? https://www.mattlewisracing.co.uk/product.php/2860/0/limited_slip_differential__triumph_herald_spitfire_tr7 https://vi.raptor.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=233036752837&category=180406&pm=1&ds=0&t=1633017026000&ver=0&cspheader=1 The Quaife: https://shop.quaife.co.uk/shop/differentials/quaife-atb-differentials/qdf8k/ I am tempted to "uprate" my Ital axle with a Backline HLF080. I don't have any plans to track so Im wondering if the tradeoffs are reasonable? Edited March 28, 2022 by IamScotticus
TheDingo8MyBaby Posted March 30, 2022 Posted March 30, 2022 From what I understand, Blackline helical is a chinese copy of the quiafe "ATB". I have heard that the perform as expected. My only experience is a Quaife ATB on an Ford "english" axle. It works well on the street; low maintenance and noise, but I found it not aggressive enough for tight/twisty hillclimb-like roads for my driving style. If anyone happens to be in the market for an quaife ATB for an english axle, let me know!
IamScotticus Posted March 30, 2022 Author Posted March 30, 2022 Edumacate me.... the "English" axle is not the Escort, right? Definitely not the Morris Ital/Marina. What street cars got English axles? Is it the same as an Atlas axle?
7Westfield Posted March 31, 2022 Posted March 31, 2022 according to the Burton catalog: "english" axle was in anglias cortina mk1/2 escort mk1/2 base model capris "atlas" axle was in capris and cortina 3/4/5 on an english axle, the gears come out the front it's a "pumpkin", like a ford 9 inch atlas has a cover on the back, like a chevy 1
TheDingo8MyBaby Posted April 1, 2022 Posted April 1, 2022 As far as I know, Atlas is just a name of the axle type. There is a lot more information here. There is also a Koln axle which is from the same era. I don't believe caterham ever used Koln or Atlas axles.
