CGT with 4Kq sway bar

[David]

 I'm putting a larger front roll bar on my CGT (using a stock 4000q bar). She is riding on Boge Turbos and stock springs (stock wheels & 185/60/14 tires). I know that by stiffing up the front only, I will cause the car to have even more understeer. But how bad will it be? IIRC, the stock bar is a 21mm and the 4000q bar is a 26 or 27. Eventually, I'll put the stock 21mm bar at the rear but for now it will be large front bar only... Thoughts/Comments?
