True, but there is still some adjustment to get the car to work with the given spring rate at the given track. One would hope so anyway.

thewird

Uh, are you serious?

Have you ever watched videos from the Nurburgring, Sebring, etc. vs. what you have at Mosport or whatever your local track is? Track surfaces are polar opposites.

If you're gonna pick a seemingly random spring rate, err on the softer side of things so at least you won't lose contact with the road and then stiffen your sway bars if you want a higher roll rate.

I don't think I'm ever going to the Nurburgring considering it is across the Atlantic. All our local tracks, Mosport, Shannonville, Dunnville, Cayuga, and Calabogie are all very similiar.

thewird

I'll be interested to see how this turns out... but without aerodynamic downforce, I can't imagine that springs that stiff aren't going to actually COST you grip.

All you want is to limit the amount that the car rolls and pitches (suspension compresses) under load... but you don't want it to be nothing. You want it to be as soft as will keep the attitude right.

I just switched to a 650/500 combo, and judging by the in-car feel, and photos of it cornering, I don't really need much more, even with 350 rwhp and 285 Hoosiers. The closest metric combo would be a 14/12 (671/558). I think Fritz is running a set he loves at 14/14, but he's got a true airfoil wing on the back, and a front splitter.

Too bad you probably won't be able to test them for a few months!

I do have a little downforce since the 99 spec wing is functional proven here at Tsukuba Circuit. I do plan on getting a REA rear diffuser and possibly have some aero work done to to the bottom of the car.

Anyway, no point in thinking too much now since I won't be able to test it until spring. I'm hopeful at least.

thewird

Sorry, misquote. 14/12 is 783/671. My combo most resembles a 12/10 (671/558). 18/16 is 1007/895.

I just think of 18/16 as 1000/900 , easier to remember :)

thewird

shit.. 5 tracks in TO?

We have one shitty track in Vancouver.. Mission Raceway.... :wallbash:

Have to drive to Seattle or Portland for anything decent.

Well, they aren't necessarily in TO, they're just within driving distance. Here's a breakdown...

Mosport: 1 hour
Dunnville and Cayuga: 1.5 hours
Shannonville: 2 hours
Calabogie: 4 hours (i haven't been to this one yet but I plan to go this year for a race weekend where they have lapping on Thursday/Friday before the weekend racing)

^ You're going to Calabogie? You crazy man you

I think it is important to remember Wird that although a race suspension has incredible adjustments and will perform better on the track the balance must be with how much street use the car will see.

For a race team looking to rebuild these racing coilovers many times during the season it is an expense of running. However, for the enthusiast the low kms per rebuild the downtime of the coilovers vs the performance gain should be taken into account. Also, you will need to be highly knowledgeable to get the best out of the higher end coils anyways.

During the summer the track does see a lot more km's on the track then on the street. Although, its my daily driver, since I work from home its not like I actually drive it everyday. It's more of a pleasure car then anything.

As for as being knowledgeable about the adjustments, I'm just gonna do it by feel. Works for tire pressures, should work for coils too.

thewird

Now permit me to be corrected by people using said products but my belief personally is that if it cannot be measured it cannot be properly set so if you do not have the proper measuring equipment in place the full advantages cannot be gained. But that is just because I always like empirical quantifiable decision making processes.

Even if you financial situation is very good one cannot be oblivious to the gain/$ ratio because money not spent on coilovers can always go to another area be it brakes, tires for the season etc. etc.

But to really answer, Penske 4 ways are the most adjustable and most expensive hehe.

When I opened this thread, I wanted to get opinions from all available options without people saying the cost per benifit ratio blah blah blah... It wasn't necessarily to get the most expensive suspension out there. I just wanted unbiased opinions which seems to be difficult in forums :P. I got what I wanted for the most part and am happy how the thread turned out.

The coil-overs I have chosen doesn't mean I think they are the best, it was just the option that I have chosen. There might have been better options but this was my choice.

I think 4-way is overkill to be honest :P and then there is the issue of it costing a ton. I'd probably spend most of my track days trying to "get it right" and never be fully happy with my settings. At least with the DG-5's, its either softer or firmer changing both compression and rebound. I'm sure I'll be able to find some settings that work for my driving style.

Or on the other side of the coin, it just won't work. We'll have to wait and see.

thewird

Hopefully we can meet at the track sometime next summer and compare and contrast our setups.

Let us know how it works out for you.

What tracks are around Montreal or which ones do you go to? Would be interesting to see some vids.

thewird

Around Montreal you have Tremblant and Mirabel which are for the most part inaccesible and super pricey. Then a few smaller dragstrips and ovals with pretend road courses nothing amazing. I am actually looking to getting on track as I have no track experience with my FD. Probably I would make it out to Calaboggie if there is an event there.

hold ish.. I just looked that track up! I need to move to TO.. That puts our one track to absolute shame.

look up `mission raceway` if you dare... :wallbash:

Tremblant looks interesting. I'll probably post in the Canadian section when im going to Calabogie since its a long drive and id take the opportunity to do 2 track days so if someone wants to come that would be cool :)

lol @ mission raceway, its not that bad, good enough to have some fun, id go to it.

And here they are along with some other goodies...

mmmmmmmmmm,REamemiya:D

beautiful... and they match your car!!!

He actually posted the rates backwards. Those coilovers are 16F, 18R

That is correct.
