Sway Bar question.
I'm looking for a recommendation on which stiffer bar selection (front and rear) for a MY13 FRS would keep the balance the same but stiffening things up a bit. When I lowered and went to sticky tires the roll increased which was expected.
Thanks in advance |

Are you on standard springs? I had the Eibach set on my car with 6k/6k springs. Yeah, the car kept quite flat cornering but I could feel the cross talk at the front through bumpy corners. I ended up taking them off and not using any sways. Because compromise.

I have Hotchkis adjustable bars, which I like, because you can tune with them.

Keep the stock sway bars and upgrade the springs to reduce body roll. It’ll allow each corner of the car to operate independently of the other.

When I was in CS (a class in autocross ) I had the TRD springs that I *think* increased rates front and rear by the same amount. (So they would not have changed the balance)
When I went with the TRD sway bars, the car's balance tilted heavy toward understeer. I ended up going with a an ST front bar on the softest setting and kept the rear TRD bar. This got me back to stock-ish balance. |

Springs or coilovers? Which kit...that'll tell others what you have?
I have the Eibach Pro Kit (1'' drop) and larger, stickier tires, so extra roll like you described is there. I have been considering a thicker front sway bar too, especially after adding front weight with my supercharger. From everything I read people have said to leave the rear alone and just slightly increase the front, yet everyone also says that a sway bar is a BandAid that would be better fixed with some good coilovers. I haven't decided if I will do a sway bar because coilovers are not on my budget at this time.

20/16 will slide more than stock but 21/16 will push more than stock. I don’t think anything can replicate the 18/14 exactly.

I've got MCA coils with stock bars, the car is on rails.
Spring rates are 6kg front 4.5kg rear. Point of note is that MCA recommendations are to keep the OEM bars as the suspension is designed to give best performance with the OEM bars. You really need to look at your handling package as a whole, otherwise you end up chasing your tail and may end up sacrificing grip. |
