That sounds like FUN! Make sure you allow enough time.

Flash and Bandit had both noted that under thrust my car seem to get down on it's haunches too much. I have new Konis and coil-overs (front only). What are the recommendations for helper springs in the the rear? 60lbs?

1000lb works well.... My rear doesn't squat much under acceleration... <img src="/forum/images/smilies/968/laugh.png" class="smilie" alt="" />

Do I need to do this before I get track tires?

Partial Post: Please Login or Register to read the full post.

typically, yes. tires are really the last link in the chain.

So- what is this solution?

Partial Post: Please Login or Register to read the full post.

[flash]

there really isn't one. the design causes sag, regardless of springs. stiffer springs help, but they won't stop it.

I was under the impression that you had a shock package that helped.

I haven't done anything about this yet. I have contemplated using the M030 rears c/w helper spring but that will raise my ride height a bit. Other than that I will have to remove the new Koni's along with the T-bar and put in a "real" coil-over with a stiffer spring.

I have the same problem, and it really shows up as under steer as you add power, weight transfer to the rear I suppose. I'm thinking a change is in order, but to what?

If I may suggest. I've run the coilover Koni 3012's on the rear that Jason at Paragon sells as a complete kit. I've put them on the last two track 968's I built, including the Riviera Blue Club Sport that Rich Tillotsen took to several PCA Club Race podium finishes. They can also be adjusted soft enough to provide a firm but still acceptable ride on the street. They are a wonderful shock for the price. There's lots more expensive stuff out there, but unless your a serious racer with exceptional skills, you'll be hard pressed to push the car even to the limits of these 3012's, let alone beyond.

Give em a look.

So what do you use on the front with these?

I had these on my E-stock setup 951, and used Koni yellow struts revalved for 350 lbs/in springs up front. Worked great. Then we used the same shocks on a 944Cup car I built with a friend of mine. Much higher rates ~425 lbs/in, but the rears worked fantastic. Make sure you get the kit with the Racer's Edge mounting bolt though. They would bind in the upper mounting point without it. I can't complain about how the fronts worked, but I know there is better out there.



I can vouch for Mikey's cars as I think I had one until my divorce...It was a beautiful M030 car that I ended up finding a set of stock shocks with coils on them, and installing. This worked, but not as well as the 3012s for sure. They are light too...

maybe i should have been clearer. you can "help" things, but the design will always result in sag on acceleration. adding springs in the rear will reduce it, but not eliminate it, therefore not a "solution"



as for me having a kit, i do have a package put together, but have not put it up on the site. in order for me to get a decent break on the shocks, i have to buy a bunch of them at once. still, the package ends up being about a grand (depending on what you choose). i think that is out of most budgets, so i haven't bothered.

So which shocks are you using?

Partial Post: Please Login or Register to read the full post.

[flash]

the are a QA-1 shock, but it's not the shock that changes the sagging. it's the additional springs. shocks only do one thing. they slow down the spring.



the kit requires not only the shocks, but also 2 sets of springs, upper bushings i have to make, lower mounts, and a coupler. it works extremely well, but it's a lot of parts, and they cost money that most people won't pay. the good news is that it is far superior to KWs, konis, and bilsteins.



unfortunately this also puts you into having to change things up front to match, and if you haven't yet gone to an adjustable coilover front, this can start to add up in a hurry.

Eric I have had great success with the Koni double adjustable struts Jason also sells.



http://www.paragon-products.com/Koni-944...42conv.htm



Again, there are lots more expensive systems you can try, but these will get you to the same very high skill level as anything from KW for a lot less $.



They are a very capable strut, with adjustable compression and rebound and adjustable ride height that allows use of standard Hypercoils. They can be made soft enough for a tolerably firm street ride, and then all the way to PCA stock class podiums. They don't have all the flashy purple anodized of KW's, but they have the edge in cost vs performance hands down IMO. Much better than the Bilstein Escorts and Firehawk systems as well



If I sound like I'm a bit biased towards steering everyone to Paragon, well, guilty I guess. I've known Jason Burkett for over 12 yrs. His shop has catered to the 944/51/68 variant more than most of the other vendors. He's honest, knowledgeable, and very helpful. As the owner of a fairly successful business, he could take his pick of high strung track toys. He owns the #4 968 Turbo RS for a reason.
