I have the prolight flywheel and the HDSS. They are great....the "High RPM lockout" is BS, adjust your pedal right and this doesnt happen. Im going to replace my HDSS...it took 25K miles of abuse...150+ launches....its a solid unit. No regrets.

 

my HDSS is holding up like a champ on my hta 35r, pushing 500+ whp through it. no lock outs here revving to 7700

 

I personally prefer the response offered by the Prolite (10.1 lbs) because of the additional weight removed versus the Streetlite (13.1 lbs.). But they will both work fine. The only drawback to the Prolite to the Streetlite is a small loss of inertia which may make it slightly more difficult to launch the car initially.

The total weight for the street disc and pressure plate is 17.15 lbs. The weight will vary based on the disc used.

 

I wouldnt worry too much about launching with the 10.1 lb flywheel... thats where the 2 step launch control thing comes in handy

 

I have the HD pressure plat with sprung 6 puck and Prolite FW and the only problem I have is launching the car. I cant get my 60ft back down to where the stock clutch was. Stock I ran 1.7 and now I am lucky to get a 1.8.

 

Got 60,000 miles out of my 2900lb ACT clutch. Now I am using the 2900lb RRE "No Name" clutch & flywheel and have 25,000 miles so far with 100 more whp than before and no issues.

Organic street discs, unless you're putting out mega power, are so much easier to deal with IMHO.

 

daryl, as far as the Prolite vs Streetlite FW's go, is the streetlite necessarily better suited for a daily driver (okay, a 430whp DD ) i.e. taking off from a dead stop (not launching, just daily driving)?

Basically, what improvement in driving will the weight loss offered by the ProLite actually give you? any improvement in acceleration?

thanks.

 

nv had a problem with mine works great! i would go with one, excellent for the price

 

I have used the 2600 ACT in all my DSM's and always loved them. Now with my Evo I figured its a no brainer. Well the high rpm lockout is indeed real and it will grind or not shift from 3-4 every time at high rpm. I tried all the remedies indicated in these forums with no relief. Its amazing that this has been reported many times, and for so long, for ACT not to correct this is really a shame. They pay the ACT rep to come on here to try to help their customers, but they should pay someone else to solve this problem.

 

I've had an ACT clutch in my SRT4 for a year now. I used a lesser version ACT when I was stock turbo and had no problems until I upgraded the turbo. With the new ACT it's right back to problem free shifting. I'll be going with the ACT on my Evo. MB7-HDSS.

 

Do you think it could be the car its self? I had a stock clutch and was getting locked out of gear above 7000rpm, I adjusted it and could shift at 8000rpm with no lock out problems. I now have the ACT 6 puck and have absolutley no problems with lock out either. I have had a few people, like 5 or 6, that had lockout issues on different clutches not just stock or ACT and I adjusted the clutch pedal and it was gone no problem.
My neighbor has 99,000 miles on his '03 and he rally races and Auto-X his Evo and he puts a new clutch in every year, ACT, and he has no problems with lockout.

I am not trying to insult your intelligence or anything, but I find it hard to believe its the clutch when I see so many Evos running ACT with no problems.

 

I went with the ACT it is a little hard to shift fast. But for the price i think it is great. Not sure about the twin though. I think when the ACT goes i might go with that. Do to the shifting is a little stiff.

 

I totally agree Erik. Its hard to beat a street disc for something that sees daily driving duties. Since the ACT w/street disc is pretty heavy I went HDSS & ProLite. I don't think it will be a problem at all with the weight of the street disc.

Off topic - Erik. We should chat. Got a TB & IM that needs some MIL.SPEC TLC.


Thanks again for your help Daryl. I much prefer honest discussions to pissing matches. Alot more gets accomplished.

 

That's odd because the clutch in your Evo 1 is the same one that I use in my Galant VR4 and I shift that car at 8500 rpm all day long on a used JDM tranny. I'm not saying that the issue is imagined but you did say that you've used our clutches before in your DSM's without issue. Two years ago we redesigned the pressure plates for the DSM's to have less travel than stock and less pedal effort than the older units we sold so we do pay someone to look at the design of our parts.

As these cars (DSM's, etc.) get older a great deal of issues can be traced to bad hydraulics, shift forks, synchros , missing dowel pins etc. As always if you feel the parts are at fault I'd be more than happy to look at them if you'd like. It's always easy to blame the parts but as cars get older (last Evo 1 was made 15 years ago) I've seen alot of these issues as a contributing factor in shifting and disengagement problems.

 

I'd save up and get the exedy twin, no lockout issues that I know about and it can hold more power if you decide to upgrade. Clutch is something you don't want to replace more than you absolutely have to because it's such a ***** to install lol
