Westfield Megabusa Alignment

[dinanminicooper]

I am planning to get my new Megabusa aligned and was wondering what would be a good setting for a car seeing 90% on track/10% on street in terms of camber front/rear, as well as caster/toe settings.

 

Thanks for any help anyone could provide!

What tires will you be running? That will affect what kind of alignment you will need.

PM me your email address and I'll send you a word doc from the factory with the official settings for the Megabusa (even includes ARB positioning and shock settings).

 

I find their recommended settings for street driven, touring oriented models are pretty conservative, but they're much closer for the track models (although camber is still understated a bit -- I'd treat the factory recommended camber settings as minimums.) Make sure your rake is set properly, as Westfields are very sensitive in this area. Don't worry about the actual ride height, which is dependant on tire size, but make sure the front to rear delta is correct (follow this link for proper measuring points.) The key is ensuring the imaginary lines between the front lower control arms' inner and outer pivot points are parallel to the ground. Adjust rear ride height from there. Also, check out the WSCC forum. There aren't a lot of Westfield owners in the US and even fewer with Megabusas, but it's a very different story in the UK.

OK, alignment reviewed today. And results are:

 

LF Camber: -1.9

RF Camber: -2.0

Front Toe OUT: 1/16"

LR Camber: -1.0

RR Camber: -1.0

Rear Toe IN: 1/16"

Front Ride Height: 100mm

Rear Ride Height: 135mm

Rake (R-F): 35mm

Nitron F: 10 clicks

Nitron R: 8 clicks

 

I am taking to track tomorrow and will see how that rake affects the beast. Might also mess around with shock clicks, but mostly excited to get the car on the track. Any hints for tire pressures (Hoosier R6s).

 

Thanks

Now thinking, alignment check done w/o my 180 lbs in car. So rake could be more towards optimum with me in it. We'll see. Will report back with video tomorrow.

I run 18lbs rear, 16lbs front on my 1100 lb Birkin (Toyo R1's). Hoosiers apparently "like" air so maybe a bit more?

Back from half day lapping, car intact, but 2 off course excursions. Have video and will post soon! Car worked great, some oversteer but in general quite a neutral setup. Hoosiers are heat cycled out I fear - got them used and not happy how they performed.
