DPT Al Dustan performance technologies coilovers

I have a new never installed set of DPT coilovers I would like to safely install on my typhoon. I know alot of this has been talked about but I want fresh feelings on this any remedies to the horrible design and unsafe setup. So here are my ideas, keep coilovers in kit and maby get them to work with stock arms with some trim work, Maby Mike Lees arm with DPT coils If Mike will just sell kit minus coilovers or last and my least favorite come up with a safe fix with DPT arms re design cut and reweld . Also I have a twin turbo ls1 setup will these coilovers be ok with the added wait of the ls1? Thanks in advance for any input advice or response of negative feelings all together about the idea of using this kit at all.

Re: DPT Al Dustan performance technologies coilovers

Ok, first off i own a set of the same arms.
second, they are not that bad, just need top of the line hiems. (Aurora, or FK Teflon lined, cromolly).
Third, i am working with my machinist to make the hiem go vertical instead of horizontal. The way they are now is not how hiem loads are meant to be used, but can as long as its not too much force.

I can draw up a design and post it here later, but i want to try my own design and test before selling it to anyone else.

Basically instead of the hiem having a single shear bolt through design i am proposing a cromolly double shear piece that goes through the spindle that takes place of the ball joint/ bolt that comes up and looks like a Y but the sides are strait and allows for the 3/4" hiem to bolt through the top of the Y and the bottom fits into the spindle and bolts down.

Not sure if i am going to drill out the spindle for a larger piece or use the stock taper that comes on the ball joint. I will probably drill it out and tig it on my truck for strength. dont know yet.

Thanks That makes me feel better about installing these. I would love to get in on the heims you are designing . please keep me updated. The welds look a little scary. I figured I could weld another tube across the arm for a little more strength.

I would just have a tig welder (pro) just run back over them. talked to my machinist today, said he was up to the challenge and said it should not cost much.

Do you have a early or late build set the early ones were not made by al and were better welded

I have been working with Al's stuff ever since it came out. I have developed a fix kit for his entire setup. the upper heim's are shimmed to actually fit the stock adjuster nuts and all the spacers are made from HT chromoly instead of crappy tubing. I have also made the balljoint adaptors with the correct taper and fit and they are of the strongest possible material instead of the junk that came with the a arm's. pm me if interested.

I believe they are the later model but the welds still dont look the greatest. I may take the advice of jpalmer and have them redone by a machinest just to be safe.

the early ones were not built by AL they were built by big sky motorsports, he designed them too the later ones were done by al in house

My opinion maybe swayed by all the issues I had with DPT overall, but the fact that a shock tower completely broke loose on my truck remains. I ended up taking everything off my truck he did and threw it away. I wouldnt hesitate to use the coilovers or shocks but I would at least do as jpalmer said and have a welder that knows his trade to go over the arms if you are going to use them. The thing I think is, this isnt like an engine part that if it went bad, you could start all over again and maybe loose money on the deal, this is a safety issue and you could get hurt bad or a lot worse. Just my 2cents.

Dustan was good at taking peoples money (a lot at that) and to date has not shipped a damn thing.

He even promised recently to ship some shocks, NADDA.

Someone needs to skin his hide IMO.

Re: DPT Al Dustan performance technologies coilovers

I know there is bad blood with that guy. I bought them from a member who went with Rpm's kit. The welds on mine are not bad, just not bitchen. I think i have all the stuff from Waller already. I have bolted the kit on my truck for test purposes and then sent it out for stripping off old powder-coat, inspected by licensed Tig welder, sent back to coaters to have fresh gloss black put on.

Next week i will get my proto-type figured out and maybe by the following have some hard pieces in my hand for pics. I may buy 7/8x3/4 hiems for the job and use misalignments to bring it back to the correct bolt diameter, this will aid in how far i can steer. I think its a good idea. http://www.offroadwarehouse.com/products/sfID1/9/sfID2/298/sfID3/305/productID/4953

And some of these in the appropriate size. http://www.polyperformance.com/shop/High-Misalignment-Spacers-p-19.html

I'll keep you all posted.

Re: DPT Al Dustan performance technologies coilovers

GREAT input from everyone . I too hate what Al did and without a doubt is a crook which is a big part of my concern . He may not at first had intentions of screwing people but he did. bringing up my concern of welds . He took on too much and just threw them together to get them out the door and forgeting about safety and quality . People selfish like Al dont care about others safety . But the thing is I have these and for finance purpose would like to get a budget fix . So Im thinking with a collaboration of Mr. Palmers ideas and Mr. Waller I can get this to work . Get the "fix kit" from waller and blast the arms re weld and re coat. If the economic times were from a few years back I would have the Rpm coilovers on my Typhoon . I love the Kit from Rpm day and night from the dpt kit . Depending on what the difference is on cost and after Im done with my custody battle and my attorney stops asking for my money I may just use my coilovers and get Rpm arms if they will work together . Thanks all of you keep the input comming.

Re: DPT Al Dustan performance technologies coilovers

I had a set of the control arms and coilovers from the last gp, can't remember if I had the rest of the parts or not. Concern about the control arms made me buy Jeffs and sell these. If I remember right my control arms are on one of Roberts syclones not sure if he did anything to them but I know he put them on. I know its not the 8 sec sy.

Good luck with the fix, I bet you will be fine with Wallers kit till you can afford something different.
