JayBee I'm interested in the excel diff outdrives, they do look cooler!
Was at bedworth BTCC this weekend testing and racing on sunday, had a good weekend putting the car in the stock A main. Luckily on saturday all the top modified lads (andy moore, chris grainger etc.) were all testing for next weeks national, so they were good to watch! I gave the SDW rear tower (2mm higher than std, I think this is what the new masami 1 does) a try, it didn't handle the bedworth bumps as well but it did provide a lot more turn-in, but it wasn't loose. In a word, impressed
The SDW tower does need some mods to work. Firstly, you need to file away at the material that would sit next to the rear diff pulley, as the tower fouls it and locks the transmission. Also, because it is narrower, you need to swap the sides your bodyposts are on, to fit the same holes in your shell. I believe this is all sorted on the masami BD rear tower.
I also spoke to chris about the new yokomo white springs. He didn't have any lb ratings but he told me the similar equivelents.
(can't remember the colour mark of the new springs so bear with me, and don't take my every word for it!)
YOK PROGRESSIVE SPRING: HPI SPRING SIMILAR RAYSPEED SPRING
softest hpi blue rayspeed green
up a grade hpi silver rayspeed blue
up a grade between silver/pink between blue/yellow
up a grade hpi pink rayspeed yellow
and so it goes on, being similar to the rayspeed springs but they give a much better feel on the track. I felt the HPI springs were a big improvement over the rayspeed ones, so the new yok springs should be good.
