Need help setting up 944 for Autocross

[porsche4life]

So is 19mm 5 way adjustable as good as I'm going to be able to get? Looks like a weltmeister or tarret bar will run north of 300

[Aslet]

The Lindsay 19mm 5 way adjustable looks like a good bar for the price. You can get the other ones, Welt is $330 and Tarret is $475, but that is a tone of money. You also need to look at the big picture. The 968 only had a 19mm rear bar with a 30mm front. The 944 is also a well balanced car, just adding a larger rear bar will start to mess with how the car was designed to handle. I agree with the other posters who say to get a good/sporty alignment and then get better tires.

I have autocrossed my 944 for a few years now and never feel like the car is plowing unless I'm making it... If you have only done 2 autocross events, maybe do a few more and make sure to take instructors to give you advice. It may just turn out that you are a little throttle happy and the front end is de-weighting in turns... I'm not trying to start an argument, I would just think if maybe the car is just reacting to your inputs and can be fixed with more careful throttle usage before you spend money and still have an issue. I also did run performance all-season tires for both seasons, and they are not the best, but should do fine to learn with.

Good luck

My thinking with the tires is that they will make the run faster and stop wear on my good street tires. I mean they are good as all seasons but they would not keep a hold on the course. The larger rear bar should take care of the understeer. Ya the M030 had a 30mm front but it was also designed to understeer from the factory.

Go with a 26.8mm front and a 18 or 19mm rear. 3 way adjustable is fine in my opinion. Gotta remember to big a rear sway bar and spinning the inside rear wheel is going to be even worse. That is assuming your car does not have LSD (like 85% of them out there).

The 30mm is indeed a big front bar. I used the 26.8 front and really liked how the car rotated with that setup. Any larger and i think understeer would have been harder to manage.

Ya I am going to call Lindsey and have them lay one of those bars out so I can pick it up next week. So my hunt begins for a 26mm front.

adding a larger rear bar will start to mess with how the car handles . that is the point . maybe i should point out why i do testing no cars . becouse i have a degree in suspension engineering .i have worked for race teams setting up cars like 911's 962's 924carrera GTR , vw rally team and untill his death paul newman . this is what you need to do before you get new anti roll bars . go get your self some books on car setups . and learn for your self what to do . your taking someones word for what works . when the truth is you don't know how good of a driver they are nor how good the car is .

[porsche4life]

Any recommended reading? I would really like to have a good grasp of this stuff. I knew I needed to stiffen the rear but not what would be a good size bar. What do you think of that Lindsey Bar?

[962porsche]

how to make your car handle . comes to mind as a good read . its an older book that was put out in the 1980's but so was your car . when i get to my shop i will take a look at what books i have and pass on what they are .

Picked up the 19mm bar from Lindsey today. Ordering the tires tomorrow and then it is off for an alignment.

YOU CANT BELIEVE EVERYTHING YOU READ ON THE INTERNET

One of the VERY VERY few things that I , and poster porsche962 would agree on is that you have no idea of of the competence of the advice you are getting . Just because one poster says " this is the way it is " doesn't mean they know their arrss from another orifice on their body .

That being said , yes do read up , research , and yes do ask for advice . The best mod you can make at this time to you and your car is to get MORE seat time to tighten the loose nut behind the wheel .

On a side note , running that Lindsey Racing 19 mm bar on the rear with the 21 mm front bar will defiantly keep your next auto x ..... lets say interesting

[962porsche]

67rschev ??? it as very common knowledge that you decrease front anti roll bar size to stop under steer . this is a fact ! why do you think most people that race front drive cars remove there front anti roll bar and start up sizing the rear bar ?????i could see you working on a race team and a driver comes in with his car pushing and you would start adding more front bar and removing rear bar . so my advice to you would be try not to be so ignorant and read up . your clearly the most ignorant person i have come across on line . you gave no good advice and only have derogatory remarks . or i should say no advice !

[porsche4life]

First who said I had a 21mm front bar? I sure didn't. 962 has proven that he knows what is going on. I came into this knowing I needed more rear bar. I just didn't know how much. As far as the alignment I just have to take his word but seeing as several trusted members have agreed I think I am in good hands.



rschev. I would suggest you play nicely for more than 10posts before you start out and out attacking members.

[flash968]

suspension setting is all about balance and completing a package

sway bar sizing is entirely dependent on spring rates - too stiff of a sway bar for the springs and you end up with a car on marbles - you won't feel it putting around on the street, and may not at the relatively low speeds of an autocross - take it out on the track, and toss it into a hairpin corner at 100mph, and you easily find an entirely different story

other factors like camber angles, toe set, ride height, and corner weighting also play heavily into the equation

nobody can give you a good recommendation on sway bar size without a lot more information

by the way, there are larger bars than the 30mm front and 19mm rear out there too - i have a 32mm front and a 22mm rear on my 968, but i have the springs and suspension to make that work

porshce4life my apologys for pissing back at 67rschev on your posting . this was the first and last time i will get in a pissing match . i try not to reply to peoples posting becouse of people like chev . i have to remember people like him have nothing and are nothing so to make him self look bigger he trys to make other people look smaller .

[962porsche]

i think porsche 4 life is talking about his bone STOCK car ? if your racing it in a stock only class then you have to put out of your mind changing to performance up grades to stay in class . you can only post date and predate the things porsche offered for that chassis . which is 924 to 968 . and that brings me full circle to find the smallest front bar and the biggest rear bar .

[porsche4life]

Ya it is bone stock. So the M030 works. Now the local PCA doesn't get too technical. In fact there are no classes. Now if I go to the SCCA I will be classed.

[962porsche]

i have never auto-x with the pca . only with scca and a like. all clubs i have raced with did class the cars .

[porsche4life]

The PCA usually does classes but my region is small enough that it doesn't matter so its just easier to run them all. We aren't super competitive.
