understeer question

[jacabean]

I am finding that my newly acquired 3.6 Boxster understeers much more than my 2.7
My 2.7 would give a nice mid-engine drift , very controlled . The 3.6 with the coilovers just tends to understeer . I know these same twisties are a lot faster in the 3.6 but i want that mid-engine sliding feeling . does anybody have a remedy for this ?

Brake alittle harder before accelrating, also, upgrading the rear sway bar can transfer the understeer into oversteer

[Adam]

What kind of alignment specs are you running? What kind and size of tires and air pressures?

Increase oversteer=stiffen rear suspension

[jacabean]

The car is still running the original Roock set up . the car is lowered way down . would actually like to lift the suspension a 1/2" or so. this will probably not help the handling situation. the roads in Mass. are really bad and the height adjustment will help a lot. What is the optimum ride height for the boxster suspension?

[Adam]

Lower is better. The ideal height is as low as you can get without scraping too badly. What kind of tires are you running? If you're losing front grip maybe try some grippier tires and if you want more oversteer then stiffen the rear like CJ and Blue said.

Agree with Adam - tires and alignment are your friend - on the track we ran 245 on front and 285 on rear=good balance for cornering and catching those GT3s

Ok , I got pirelli p-zero asimmetrico tires , 225-40 front 285-30 rear 18" . the car has a set of H&R coilovers and the factory M030 package. So if I lift the entire car a 1/2" or so how will this change the handling? I do not have the alignment specs. what do you guys think is the simplest way to adjust the car for street use. I do not track this car. just some crazy back road blasts .

At least part of your understeer problem has to do with the extra wide tires you have on the rear. You need wider tires up front as well, like a 245 to balance out the back. The Pirelli's you have are ok, but there are better street tires out there for ultimate grip. Look into Kuhmo XS, Bridgestone RE-11, or Dunlop Star Specs. On a well set up car you'd have to have a death wish to overwhelm those tires on the street.
