He's been doing this the entire thread. Compares track setups as suitable for street use. It's quite hilarious.

I know all about this! But luckily it happened on the way to the track and not at the track.

I think everyone needs to take what they are seeing with a grain of salt as well. You cannot compare travel limits on an EVO front vs REAR or a SUBARU vs a GT3.

They are not the same layout, motion ratios, or even setup from the design board.
A 430 challenge ... seriously, how can you compare the travel on a car that was built and designed from the drawing board to do one thing : GO FAST AROUND THE TRACK to an OEM evo or subaru?

Not reading the thread at all, how do stiff swaybars affect the first pictures?

edit: looks like none since both fronts are off the ground

That's a GD STi with RCE T1 with the 500/500lbf/in springs. The track is Streets of Willow Springs. Note the amount of travel used. The damper is cycling through its full range of travel repeatedly.

I should also mention that this was his first outing on the Tarmacs at Willow. Compared to his previous coilovers, he dropped 3 seconds off his lap time with no other changes.


His previous coilovers? Megan Racing.

I hope I can see 3 seconds of improvement from my new kw v3s compared to my jic flt-a2 setup. Since I have kept the same tires, wheels, brakes and alignment settings, it will be interesting to see at buttonwillow. I can say that ride comfort and stability is better so far. The difference in braking on bumpy surfaces is amazing. The spring rates of the linear springs is unchanged, 8kg/6kg.

So, basically, the only change is damper. I for one am VERY interested in seeing the changes in time. Please post them up when you get a chance.

The actual springs are different as well. The jic had their springs on them and the kw has swift in the rear and kw stock ones up front. I got the STi fitment since I liked the front being an 8kg+ helper spring.
The track temps look to be similar to last events so I will definitely post the data. The event is in June, I'm still doing shakedown right now with ride height adjustment. The jic were much lower and the car looks funny to me now.

Using dspecs and ground controls i should have the ability to dial sufficient enough drooop to warrant helpers wouldnt u think?. i think this setup would be stiff street but still managable. im thinking of using 8" springs all the way around, 400f/350r 99 impreza/gdsubframes control arms etc.. im also using lowering camber plates upfront with a roll center kit

And finally on the 8th page, the most pertinent question (rhetoric ) is asked.

Have a vehicle that can generate enough lateral grip to transfer its entire weight to the outside tires and droop travel does not freaking matter! Also, it really is amazing how a thread on suspension went on for so long with no talk of weight transfer.

Also, discussing how one suspension setup is better than another without full knowledge of the track surface is just... One set of compromises for a particular track might not work for another. To distill it down, one must juggle ultimate steady-state grip over flat surfaces with that over bump surfaces.

So we should change the thread title to "cheap coilvers are good for smooth tracks".

First of all, take a look at the video in comment 410. Car on smooth track. Car using more travel than cheap crap coilovers have. End of that line of discussion.

As far as Mind's question that you quoted, that's largely down to the kind of diffs the car is using. As long as the inside wheels are touching the ground, the car has not transferred 100% of the load to the outside wheels. Depending on what kind of diffs you're running, this can be the difference between the diff acting like it's open and it continuing to act like a LS diff. Additionally, so long as the as the inside wheels is touching the ground, it's contributing some to the lateral grip of the car. It may not be huge, but we're chasing after fractions here anyway.

I know, but some people just argue and say that stiffer springs=les required travel. I dont know whats best for the track, but I beleive I am staying with a strut on the street for a reason.

However, no matter how lightly sprung it may be, an inside wheel which has been unloaded 99.9999 percent has got to be better than one who is 100% in my line of thought. Does anyone have thoughts there?

That car on the smooth track in post 410 had 500lbf/in springs. How much stiffer are people talking about? You're already in non-street-legal tire territory there.

Your argument here is sorta flawed here and im gonna throw it up as the driver getting more experience then the dampers for the 3 seconds..

in the video hes averaging around the 1:40-1:44 range at sow cw... most stock sti's will run a 1:35 range at this track. so you can see that if we're using your example a lightly sprung stock shock is better then a coilover on the track.

If this was a car running 1:25 and shed 3 seconds.. different story. Altho i do love my kw's.

I'm not sure it's an STi. I'm fairly sure he's got a WRX but I'll have to ask. Being down considerably on HP would raise his overall times.

If that's Saul_Good's (not sure of his real name) car in the SOW video it's actually an 05 LGT. Thus not comparable to stock STi lap time. The switch from Megans to proper coilovers at that track could definitely net you that sort of time. Anyone that ever exited the bowl there flat out and crested the small hill that comes after it just before dropping into the next set of turns can tell you how nice it is to have some droop travel there.

Subtracting the mechanical grip advantage of proper working coilovers from the equation for a second lets not forget how important it is just to have a suspension that gives you confidence to find more speed. It's hard to go flat out in a car that feels skittish and nervous everywhere.

A really good driver can be pretty damn quick in anything, but even quicker in something that's working well.
