Rear Spring

[Uaintlobusa]

I am looking to put a 6 inch stretch swingarm with a 240 tire. on my 2006 LE. I am 6'5" about 300 lbs.
I had stretched my 2001 Busa 4", and the stock shock was too soft.
I need a stronger tighter rear spring. I contacted Eibach, they said they dont have a Hayabusa listed in there system, but If I told them the spring rate of the stock spring, they could probibly get me something tighter.
I dont want to put in a strut.
Can anyone help me

We carry aftermarket springs for the busa and 240 kits.

You'll need to look at revalving the shock as well.

Look on the race tech site. I believe the stock spring rate is 13.1 .
