VTEC Subframe for Classic Mini B16/B18
*****2019 product facelift*****
2017 features redesigned mandrel bent chassis rails and engine support rails.
2019 March on features further aesthetic enhancements to the b series vtec subframe.
As with every Allspeed subframe, the product is all new material manufactured by ourselves. Every subframe has gone through an extensive design and fea stress analysis progamme. Our subframes are not to be confused or compared with cut and shut 'a' series subframes or reverse engineered products. The Allspeed product is the original and designed from the outset for the application and manufactured to the highest standards.
The frame is all brand new and uses the standard b16a2/c6 5th gen EG/DC2/MB6 top mounts with a bespoke rear mount included with the frame. It is designed for the b16a2 and although the design offers flexibility for mounting other engines will only guarantee fitment of the b16a2.As with all our frames the b16a2 frame can use the rubber donut/coil spring replacement or coilovers, and all with standard track and wheel base.The frame and engine/gearbox assembly will fit a standard round nose but room for an adequate size radiator and good flowing exhaust manifold will be a challenge to overcome.
As with any classic mini, suspension setup is crucial , this issue is even more of a priority with high power conversions using basic mini suspension geometry, wheel alignment, corner weighting, bump steer correction and keeping scrub radius to a minimum will all enhance the driving pleasure of the completed conversion. Please refer to faq for some handy setup tips.
If attempting fitment into a standard round nose would also recommend a flip front as the size of the engine/gearbox assembly will be extremely tight to fit through the bonnet opening.Use of the standard injection phlenum and ecu will require bulkhead mods, these can be minimised by cutting angling upwards and rewelding the inlet manifold. Use of itb throttle injection can be done without bulkhead mods.
The stock Honda gearstick and linkage rods can be used but shortened to suit the mini driving position, it is recommended to replace the stock bulky linkage universal joint with an aftermarket compact precision linkage universal joint, to improve the gearchange quality and also offers more clearance between the uj and subframe.
The subframe is designed for spherical jointed bottom arm and tie bars, the allspeed items are plug and play with the subframe, it may be possible to modify or adapt others to fit.
