HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Need help with suspension

Post  Arthropraxis on Wed Feb 17, 2010 7:54 pm

The car is an 87 turbo and will be street driven with the potential to doing some DE events in the future.

upgraded castor blocks
koni sport inserts front (hacksaw method)
koni sport rear shocks
track ball joint rebuilt kit ( I took them out and the plastic cups on both were shattered )
front bushing for both control arms
paragons adjustable ride height kit with 250# springs

I was not going to originally go with heavier springs or the adjustable ride height kit but I don't want to do this again later.
Any input is welcome. I want to order this in the next few days so I can get started on it.

I have 250# all around and it's great on the street. Some have suggested going to 300# in the front while keeping a 250# rear. Sounds like a good setup to me!

When you say 250# rear do you mean rear coil over helper springs? I am just planning on the shocks only and stock turbo torsion bars for now. I read about re-indexing and that does not sound like fun.
BTW, I already have the M030 968 front and rear stabilizer bars the original owner bought prior to blowing the motor.

I actually upgraded the rear torsion bars to 28mm (roughly 250#). So i suppose that would be the same as adding 100# springs to the rear?
Mine also has the 968 m030 sways, and i have koni yellows.
I didn't have to re-index at all (there's enough adjustment in the eccentric), but i did buy the elephant racing spherical bronze bushings and those added quite a bit of cost.

I have read how hard the torsion bars are to change. What was your experience?

There was an excellent thread over at Rennlist on this topic. It gets very detailed about spring rates and calculating F/R balance.

Cant post a direct link but here is the path....

I read that post, it makes me question my intelligence. I read the how to on paragon's site about changing the torsion bars and it sounds like a huge PITA. On rennlist there are several posts that go either way on changing the bars for 250# front springs. If the 225# front springs are enough to offset the LS1 weight they would be a better match for the stock torsion bars. I am going to get the adjustable ride height kit to allow for raising/lowering the front if needed to balance it out.

Since this is brought up here, I might as well throw out my idea; I have a local uber engineer that has been making BMWs tick faster and harder for years now. He even designed a coilover system for the E36 and E46 platforms. So far, when time and money are situated, we may design and introduce a coilover system for the 944s. To me, at least compared to the options out there for BMW, the 944 gets shafted in this area. No matter what you look to do, it will end up costing an arm and leg. Hopefully our coilovers will be resonabily priced and properly designed around not only the chassis, but also our engine swaps (as an option). For more information on my engineer friend, his site is http://www.racersmarket.net/

If my plan comes into fruition, there would be no doubt that you guys would be considered first for testing and the likes.

Ordered from paragon and changed to 225# springs to better match the stock rear torsion bars.

Curious about rear squat under acceleration. Are the torsion bar and shocks enough to counter act this with the LSx or are coil overs also required in the rear?

I have read that the factory torsion bars aren't enough for the factory turbo car to not squat so this will probably take off like a speedboat now.
