I think I am regretting my spring selection
 

I ended up with 14k springs in the front. I am starting to regret it as I think it is too stiff, I probably should have gone with 12 and a big bar instead of 14. What do u guys think

Personally, yes. WO aero 14k is kinda stiff. The OEM setup has a wheel rate of about 167 in the front and 146 in the rear.That calculates out to a a ride frequency of about 1 with a 15% difference front/rear.

14K frontis 300+ wheel rate and a >=2.0 Hz ride frequency which is definitely above or at the upper limits of where a non aero sedan type car should be.

as a general guideline:
 0.5 - 1.5 Hz for passenger cars
 1.5 - 2.0 Hz for sedan racecars and moderate downforce formula cars
 3.0 - 5.0+ Hz for high downforce racecars

So unless you have a pretty significant splitter, you might want to tone it down.(Or buy a splitter!)

I violently disagree with the frequency guidelines above. You won't find a formula car with 1.5hz frequencies on planet earth. Most GT based race cars are 3hz+ and formula cars are over 4. 14k is not all that stiff in reality.

just curious, what about it seems "too stiff", also what dampers are you running?

Formula 1 no. Formula 5000, probably. I don't have specs on either one nor am I friends with any drivers from either one. But without Aero, I can not see any reason to use anything stiffer than 14K on a road course that has bumps, camber, and traction changes.

In a nice flat Auto X environment I can see the point. 14K spring with a corner weight of ~800 lbs is pushing the limit of tire compliance and would only be good on a very smooth flat surface-like auto X or tarmac. You will not be getting enough bump travel to ensure tire compliance. I don't know the math on bump stop rubbers, but proper bump stops is probably a better answer than 18K springs whether on tarmac or corner 6 of Big Willow.

Sorry man, but you are WAY out of alignment with what actual race cars use...

Even FSAE cars are well above 4hz.

Also, while most of the West Coast Auto-x sites are pretty flat...it's the opposite on the right coast. Our sites are mostly bumpy as ****...

waiting for the rest of the car's suspension specs before i give some input.
but in my opinion, a 370 on wide front tires at a good pace, 14kg isnt outta the question, but the damper needs to be up to snuff

Well then I apologize on believing in basic math. A small note though, if your front right tire is 8+ inches off the ground, you suspension is probably not tuned right and you need to reduce your spring rate. TY for proving my point with your photo demonstrating a terrible suspension.

I find this bordering on hysterical, but do carry on...

..it is "jacked" up because he hit a bump at 50mph while accelerating out of constant radius corner.

Also, although I don't agree with Dennis Grant at all on set-up, he does supply an easy to use dynamics calculator on his website...

Just out of curiosity, I looked up what a bog standard 996 GT3 cup car came with for springs....1200lb on front, with a strut.....on car with no weight on the front wheels. Then again, I am sure the fine folks at Porsche motorsport are just plain stupid and haven't discovered the internet knows all.

I'm just trying to think of that race where the winner had two wheels off the ground. Oh yeah now I remember, the Dukes of Hazard, those guys were fast! I bet they were using like 5000Hz wheel rates to get away from Boss Hog!

You must not watch any touring car racing....

Umm that's not a touring track on television, that's a parking lot with cones.
