Car is very close to my liking now as I can manipulate what I'd like to do after apex, splitter addition and removable of the front swaybar have done wonders! Car when loaded up out of a corner is 3 wheeling so I'm going up in spring rate from the current 750/900. Now I just need a new diff!

No sway bars or just the rear?

No bar front or rear. Bimmerworld is wanting me to try the springrate increase first and then possibly a stock front bar. I've gotta be honest I'm really happy with how the car could be manipulated at NCM. I think it's a great track to be able to learn your car at. It's got a bit of everything but most importantly it's got corners you load your car up and keep it there for almost 5 seconds. Not many tracks offer the ability to slowly increase speed Ina corner to be able to test the limit

I run a stock front bar and no rear bar with 450/700 springs. I need more rear spring but the car just sits down when I get on the gas. I can put down the power and get a great jump out of the corners on much higher HP cars. I really like no rear bar. Not so sure about the front. I also have aero. Right now, it is a little bit too biased to the rear. I can drive around it, just need to trail brake deeper to the apex. I would love to get a little more front bias on the downforce.

I like the front end to be a little sharper which is why I don't think I'll like no front bar.

That's the thing though, no front bar will give you more front bite. It obviously won't give you more aero bias to the front, but it will move the balance forward. Think about it, your bar is lifting your inside tire off the ground..... Can you adjust your dampers to compensate for no front bar and keep the front end sharp?

Maybe you need stiffer front springs? Hank at bimmerworld corrected me when I thought lower springrate = more grip. He said it was actually the opposite, as the higher spring rate drives the tire down into the asphault. Even without a front bar I'm still 3 wheeling coming out of corners and Hank is telling me it's due to suspension geometry. The only way to eliminate it is with spring rates I wouldn't want.

On a different note, if you have the chance to get to Ozarks you really need to go, it's AMAZING! I'll be going for the 3rd time in a year the end of this month with KCPCA because it's that good.

it depends. I think there’s a target freq rate depending on surface and aero load. I’d argue I have a lot more grip running softer springs on bumpy tracks.

I can add some splitter tunnels which I think will rebalance the car to be more on the front axle.

I’d like to get there but its a haul. Does BMWCCA run there? I tend to avoid PCA. Some chapters are a pain in the ass.

I get what you're saying about softer on bumpy...... Those tracks aren't worth going to anymore. There are too many good options out there. For me that would be Hallett, super fun track when I had my ZHP but the last time I was there I swore it off until it got repaved. Which I hear actually happened this past winter.

No, no BMWCCA there, we run KCPCA there and they're very hands off, good chapter. I know it's a haul but I guarantee it will be worth it. It's in my top 5
