the 03 and 04 have a viscous coupling for a center diff, not a LSD. You should be OK to add a front diff.

 

They still have a rear LSD though, correct? Then you still can't add a front LSD.

 

viscous coupling is a type of LSD

 

I completely understand the can o worms that can occur by allowing updating/backdating. That's why I only mentioned the front LSD allowance. Otherwise, selling a 03/04 and buying a IX (maybe X?) starts to make a lot more sense.

 

Exactly ... If the front LSD is an issue and you don't want to run BSP/SM, then the only other recourse is to sell the 03/04 non-front LSD EVO and get an 04 RS/ 05+ EVO with front LSD, ie. if you are dead set on running in STU. Nobody said this sport was fair or cheap ... Unfortunately the rules are the rules ... if you don't like it write a letter to the SEB about it, who knows they may implement changes ... but chances of that happening are grim.

 

Yup.

Alternatively, you can just deal and move on. 03s can and did trophy at nationals last year. I don't think there is any driver would do really well with the FLSD but couldn't do well without it.

I would be in favor a "simple" RS conversion: add FLSD, remove ABS. That gets you what is basically my car but with a bunch of random tidbits that don't help performance anyway. Of course, I have no motivation to propose it to the SEB because I already have one.

Yes, this is one of the reasons I came close to selling my '03. For now I have just accepted the fact my my level of driving and participation is not yet high enough to warrant or this, so I am just going to try to learn with what I have. My driving ins't competitive, so my car does not need to be either right now. I was just whining about its limitations on principle. If I ever do become more serious and feel I will want to try to be compeptive, the I guess I'll have to choose between changing to a different car and keeping the same class, or changing to a different class and keeping the same car. Carry on.

 

Since its obviously f'd up I would install the FLSD and keep your mouth shut.

Good driver or not... the LSD was a GIGANTIC improvement in handling when I added it to my 03.

 

I don't notice any front inside tire spin on my open diff 8. I can't tell any difference when driving newer Evos with a front LSD. I have my suspension set up for the open diff. I would think the rear diff would make a greater difference in BSP/SM.

 

Rick,

When are you going to get rid of that slow dinosaur...... You don't have enough torque to spin your inside front....

Dave

 

Then you are very lucky. Have you tried driving other cars with FLSD and ACD?

 

Sorry to go off your guys discussion but I didn't want to make a new thread. Anyways I am looking for some coilovers to probably run STU part of this year. Anyways I had it narrowed down to Ohlins DFV, ZZYZX Sports, or Robispec KW3 but I dont think I can afford those this year so I might try Stance GR+ or PIC R1 Selects for fairly cheap since they seem to work well. My question is Stances stock springrates are 9kf and 8kr. I was wondering should I flip them and do 8kf and 9kr or just get 8kf and 10kr (these are the stock rates on the PIC's.) I will be running 245 RE01R also. What has most people had luck with for mild springrates like such (my car is a daily driver and I dont race nationally so I enjoy some ride quality) Also has anybody had much experience with those two sub $1500 coilovers.

Or should I just save up an extra $1200 for the Ohlins DFV. Then run on my current setup (besides boost controller)

 

Don't waste your time and $$. Spend it once on what you really want and forsee yourself using in the future.

 

Bingo! What Kekek said. Don't waste your time and money with the cheap stuff, do it once and do it well.

Here's a little summary overview between ZZYZX EM, KW V3 and Ohlins that may help with your decision:

1. ZZYZX EM: Twin tube, Fronts are not inverted McPhereson design, no seperate spring preload and height adjustment, but great range of adjustment, 1way or 2way depending on the model you purchase, steel construction.
2. KW V3: Twin tube, Fronts are not inverted McPherson design, no seperate spring preload and height adjustment, 2 way adjustable (compression and rebound), good range, stainless steel construction
3. Ohlins DFV: Monotube, Front are inverted McPhereson design, seperate spring preload and height adjustment, one way adjustable (rebound), very good range, stainless steel and aluminum construction.

People have a tendency to hype one coilover over another without giving the technical details ... Hope this helps in your decision.

 

I think the twintube/monotube debate is completely overblown by shock manufacturers. The build quality and valving design are more important. Some twintubes are craps, but so are lot monotubes.

If you read the SAE shock absorber hand book (by Dixon) it says straight up that the only real difference you should consider when choosing a design is that twintube shocks can't be mounted sideways (as in a formula car).
