S15s can and will under steer. Gotta be carefull especially when you get into a bad weight transfer situation. Example, too much weight at the front than sudden heavy braking followed by immediate hard acceleration.thx mazzy and all others who have so far replied to this thread, keep em coming!!
topper: how much power are u running atm? btw in relation to power to grip coming out of a corner, is the biggest problem the torque we have which causes the grip to break traction?
so with alignment, is that just making sure all 4 wheels are pointing at a constant/same direction?
to my knowledge, is toe-in when you put your wheels into each other like this? " / \ " of course not that extreme but you get the idea =D
-- just my opinion about the stock S15 suspension
i feel the rear end gets unsettle quite easily. what i mean by this is during a corner the slightest bump will cause the rear to take a leap and it takes a long time for the rear suspension to 'rebound?" back onto the road and during that time when the rear tyres are not contacting is where we lose quite a bit of grip/confidence to the driver to continue accelerating
the car does have a slight tendency to understeer when u initially try to turn in but when you start applying power it smooths out the line you take and eventually lose traction but im not sure if im correct on this but it feels like the car is not in 1 peice, the front end will go in, but it just takes wot feels like a long time before the rear end follows and tucks inside into the line you want - i guess to help solve this would be to have struts?
this is just the feeling the stock s15 suspension gives me, i could be totally wrong but im just going on how i feel when im driving it. or im just a total noob and hav no idea what is going on =)
Again, this happens only when suspension settings are off or if the front end is too soft (ie stock suspension).
Thats why as a couple have mentioned, 1st best step is to go for decently good coilovers. 1st best investment besides anything else.
