Tightening the Rear

[wparsons]

OP, what kind of conditions are you driving in as well? What's your driving background? Are you on the gas too soon?

I can make mine step way out at ~40km/h in 2nd by getting on the power way too soon (on purpose), but if I'm driving "properly" it's VERY well behaved at ~60km/h in 2nd.

I just did a driving school last weekend, which included skid pad sessions, and I had to really try to get the rear end out of line with 225/45/17 Dunlop Z2's. The surefire way is to get it right at the lateral limit in the meat of the powerband, lift hard, then punch the throttle. Driving smoothly it just wanted to stick and go.

Hey sorry for disappearing... Right now I have 215/45/17 enkei rpf1s with hankook v12s.. Great feedback...I guess my other ? Is are coil overs worth it? I had a set of KWs on my genesis coupe and they made a great difference on there..I'm unsure if it will make the handling better on a car already this well sorted

V3's definitely won't hurt the handling at all, but they won't drastically change the balance either unless you go with custom rate springs. If you're finding the rear gets away under power you'll have to do something else.

It doesn't hurt to get a second opinion, I let a couple instructors take my car for a few laps and they couldn't believe how much turn in it has, and how easy it is to drive fast. One of them owns an S2000 and said he actually likes the FR-S better on a track. Mine is 100% stock other than the wheels/tires.

Buddy has this problem with his but the rear won't stick due to turbo. He has kwv3 and actually switched the front springs to his rears and vice versa and that helped a lot. Might wanna look into some could n figure out a spring rate you'll like. Ask around n post a thread on that subject and see what peeps tell ya

in case you ignored the piece of advice earlier, start with an alignment.

I bet his car pushes like crazy into corners now until he gives it a bunch of throttle to power oversteer?

The better solution is to run more tire out back and maybe a bit less camber, then increase the spring rate to keep the off power balance the same.

Isnt it true that when you add more weight (hence more grip) at the back it'll understeer?

Why on earth would you add weight? This would have to be the most counterproductive idea I've seen. Let's add 100 kgs front AND rear (just to keep it balanced). That will improve grip for sure.

As stated in the previous posts, someone said adding weight to the back would be good coz it'll add more grip to the back.

People REALLY need to stop suggesting adding weight to the back to improve handling.

The ONLY place where adding weight to the back might help is for drag racing or driving in more than a dusting of snow.

If you're concerned with how a car handles corners you should look at where the weight is transfering under braking, cornering, etc. If you're going to mess with corner weights you should REALLY know the effects before doing anything, including knowing what you need to do to the spring rates to keep the car's dynamic balance how you want it.

no it wont. its kinda why cars like the frs, elise, miata,etc will outhandle a lot of the more serious, faster cars.
