BRZ stock suspension on FR-S

I would like to eliminate some of the oversteer in the FR-S but I don't want to spend a fortune in a suspension package. I'm not interested in lowering my car.

Easiest way to change the handling is by installing a BRZ suspension. Has anybody done it? Happy with the results??

Thanks

Just took off my BRZ suspension and installed KW Clubsports. Would be happy to sell you mine if you like.

You may want to look into a bigger front bar and/or stiffer front springs to reduce the oversteer and it won't cost a fortune

IIRC the only difference is that the BRZ has stiffer springs so that would probably be the cheapest route. I'd look in the members classified since a lot of people have made the switch to coilovers.

BRZ has stiffer front springs, that's all you need.

I'm currently running FRS rear springs on my BRZ and I love how it handles. As mentioned its also a good idea to run a stiffer front swaybar to keep the rear tires on the ground and the diff doing its job. Also some front camber bolts will help as well.

When do you oversteer? The FRS understeers in steady state cornering...

just unhook one of the endlinks on the rear swaybar. thats free so i would at least check to see what that does before you go and do something that radical.

This! If you're getting oversteer only under power then the BRZ suspension isn't going to help you, you need to learn how to drive a RWD car properly.

They're both pretty neutral, but if you try to carry too much speed into a corner both will push, and if you get on the gas too soon both will want to spin.

I'm surprised by both of these posts. We owned an FR-S for 3 months, it was T-boned and totaled, and we got a BRZ. The BRZ is neutral, the FR-S liked to rotate. You can make either car rotate or push with the right application of inputs, but the difference in tendency is pretty clear.

That is a very unfortunate incident and I'm glad to hear you picked up one of the twins. The BRZ and FRS have almost no difference although the FRS does respond better to our preferences on track. Upon track use, neither vehicle has shown any significant difference. In fact, the FRS is closer to a neutral feel than anything. The more neutral the car feels, the more "loose" it feels. 91 MR2s and AP1 S2000s are more "oversteery" and rotate much faster than a FRS.

Here is a FRS on TEIN SRC which actually is set to have a more neutral suspension setup (10k/12k spring rates). It rotates much better than stock.

Did you stick with the BRZ dampers? Any noticeable change in ride?

Thanks!

Maybe mods to "limit throttle on oversteer" would better describe what they are after?

Yep I agree. The stock FR-S is close to neutral, but will understeer when you're at the limit. If you give more than maintenance throttle at that point, the rear end will come around gently. I really like the balance of the car from the factory. It seems to fit my driving style and skill level (or lack thereof haha). Will make you look like a hero as you ride that line on corner exit.
