I'm going to buy a set of cal tracs for my 70 stang and they told me to also purchase some Rancho 9000 shocks part number 99159 which is listed for a Land Rover. Has anyone tried this? I purchased the shocks and will try them without cal tracs this up coming weekend at the track. I will let you know how they work.------------------

I put #RS-9204 Rancho 5-way adjustable shocks on the rear of '69FB. You may want to double-check that part#.......... ------------------

Your absolutely right Ryan! I changed my order to the 99204's. Calvert has the 99204 for the 69 stang and 99159 for the 70 through 73. I explained to them that the 69 and 70's are basically the same and hopefully it wont happen to someone else.
Thanks again,
BrianWhat 60 fts are you getting Ryan and did the shocks help you at all? What other traction aids are you using?

Although I'm still getting wheel spin, I'm averaging 1.77 60'ers. I'm sure the Rancho's will help, but I'm still trying to get them tuned in... I haven't had enough GOOD track time to get them figured out for my car. When the track is crappy most of the time & nearly EVERYONE is spinning, how can a fella hook up? I also have a set of Cal-Tracs (which also need their preload fine-tuned) to 9" slicks. I'm hoping to improve my traction by getting more front end weight transfer (increased pitch rotation) with the installation of a pair flat top shock mounts up front and notching the frame rails a bit under the upper A-arm.

I'm averaging 1.58-1.60 when hooking and 1.65 when slipping. I have a stock set up with slapper bars and 50/50 rear shocks and 70/30 fronts. I was hoping these shocks would be the cure but if your spinning with 1.7's I'm a bit worried.

Brian,Rancho shocks with slapper bars help, but you've got to adjust them for track conditions. Loose for a poor track and tighter for a sticky track. The problem with this system is that they aren't very consistant and conditions vary between rounds. Ranchos coupled with caltracs give you a lot of adjustability for different track conditions. And, if you set them for poor conditions they will still work about the same 60'ers when conditions improve. Great for bracket racing! But if you want to set them for a sticky track you can really lower the 60'ers and pull the front end off the ground.  SteveW

Those are nice 60' times, Brian! If I were you, as funding allows, I'd still step up to the Cal-Tracs and the rear Rancho 5-way shocks. You may also consider setting your front shocks to the 90/10 setting. As SteveW said, that setup gives you more adjustability with varying track conditions. I'm confident that I'll be able to improve my 60' (and 1/4) times too. As SteveW also mentioned, it takes some tuning - and that's what I haven't be able to zero-in on yet. I'm also thinking that maybe my worn slicks may be too far gone to bite like they should.... Good Luck!

I have the 99159 Ranchos with Cal-tracs on a '71 Mustang. The shocks are listed for a Land Rover but they fit the Mustang properly. The advantage of this shock over the standard shock listed for the Mustang is that it has more travel and is longer. It eliminates the possiblity of the shock "topping out" which can happen with the standard length shock in a drag race situation. You don't need much down travel on the rear shocks, but they need to be able to extend quite a distance. I have seen several cars with standard length shocks with extensions on the studs to prevent this from happening, but the Rancho solution is a lot cleaner.

Several years ago when I ordered a set of Caltracs, John Calvert gave me part numbers for two shocks.The first was the #9204, the second I don't remember. The second one was just like the #9204, except it was longer. He said the vast majority of cars do fine with the #9204. The #9204's fit my car perfectly. I would not want a longer shock, as it would probably bottom out on bumps when street driving. The #9204 is plenty long enough for my 66. Good Luck! ------------------

Well, the shocks are in and I went to the track today. The car ran fairly consistant 1.584-1.599 with changing weather conditions. I had it set in the middle #5 as it goes from 1-9 on these. One run was a 1.66 with wheel spin but atleast it wasnt in elims. I'm sure with a sticky track if I tightened it up my 60's would be even better but I play with that on a test and tune day.
By the way I ran another all time best of 11.833 so I'm going in the right direction.
90/10's are next in the front.------------------
