As the title says, are sway bars totally personal / car specific or is a known size determined to be most suitable for our cars.

Car is running well and next step is to sort out the on track behaviour.

The Koni shocks I have allow a bit more body roll mid corner and I think the turn in could be improved somewhat with a set of stiffer sway bars.

The previous owner of my shocks, engine, wheels etc ran 24mm front (15/16 ish) and I think 16mm rear bars. this was a relatively succesfull race car in our "classic Japanese" series.

Is this the right size to start with or do you race / track guys have other ideas....?

160 HP (soon to be 240 engine swap in the next few weeks)
Dunlop Direzza Semi Slick 205 x 50 x 15 on 7" rim.
Koni race type shock 10kg fr - 6 kg Rr Springs.
Original Goodwin Racing BBR kit (11" front)

 

I have a 24mm front and 14mm rear and felt the on track balance was pretty good on my NA.

 

Follow the 949 formula. A balanced car has a formula and that's spring rate and sway bar. Make your personal adjustments with alignment and damper settings. However, I will concede that they way I set-up my car (after Emilio helped me with bump stops) is the same way Emilio likes his cars, the way JohnWag likes his car, and was very similar to Crusher.

 

Direzza semi-slicks? I haven't heard of those I didnt know they had an intermediate. I know bridgestone is coming out with a sub 140 tw tire (RE11S) but didnt hear of dunlop. Bars depend on the type of racing and what you have going on spring wise.

 

Based on the username, I'm thinking he's in New Zealand.

 

I know, and I'm hoping he gets the sexy new tire choices that are coming to the USA next summer, at the same time Japan does (aka now).
