So I am 6'5" 212lbs, 232lbs with gear with a slightly heavier Corbin seat... call it 8-10 lbs more.
Race-tech recommends a 1.01kg spring for my weight up front, and a 15.3 rear. (stock being 14.2)

They don't sell my rear or close to it so I was going to go penske after this summer. But I want to try to do the front end right away. Is that ok?

Will doing this spring, with rebound on front, be a bad thing to do before the stock rear is replaced?
Will the ride and feel be too far unbalanced? Or is it just a bit rougher but balanced enough on full preload in the rear.

 

It should be an incremental upgrade. If the front end is able to better follow the pavement, it will have an immediate, positive effect on ride quality.

So it should not upset the balance and make it push into a corner under hard lean with the front being a stiffer setup than the rear?
