    Thank you very much good sir, the pic's and information are truly helpful.
    Also your method of doing it.
    You have been a tremendous help, I hope one day to help you out in return one day.
    I fell so far into the crawling side of the hobby for a bit I put a lot of the go fast stuff on hold.
    That said summers coming and I've messed around long enough; time to go fast again.
    My mounts will be here tomorrow; there in Allen park now but I want to get this darn fountain for the wife done.
    The water and designee is no issue,tho the five colors of dimming LED's is a bit more of a challenge.
    Thank you again for the pics and in formation.

    If you can get a mm number between these points after the cut it would be excellent.
    No problem if you cant no worries, I'm sure I can get it right with the info you've already supplied.

    You are very welcome.
    The side pieces are a little tougher to do. Compared to the front and rear.

    Are you talking about the parts above and below the arrow?

    After some quick crude measuring your numbers look about dead on.

    The side pieces getting them cut right is tougher then putting the front and rear diffuser

    Did you do this by hand or own/have access to a cnc cutter.

    Well you did a very good job, in fact excellent.
    Sounds like I need to buy a couple new blades if I'm going to try it.
    I really like the idea and the way it came out.
    Some nice cutting Er33.

    Thank you very much billy. It was fun building it. I had to get the measurement from radreptiles on how long the cutted piece was suppose to be. After that it was tracing cutting and drilling new holes. I was a little nervous doing it but was happy with end results

    Would like your input please.
    I have and am considering putting XO-1 shock towers on the PF-8 build.
    I'm not sure if I'll be buying another body or just making a new set of holes on this one.
    Do you think its worth it or stay with the strc mounts and original body holes?

    The hole point is to keep the XO-1 tunnels/rear diffuser as close to the chassis with out cutting holes in it.
    If it comes down to it I'll cut the tunnel mounting holes off them first as there are multiple ways of reinforcing them.

    Doesn't your body already sit low enough? How does your xo-1 diffuser look like now on the rear. How I'm reading it you didn't cut into it where the arms are which sits lower which then brings the side pieces down more. Is that how I'm taking it? You could modify how the front diffuser will mount to the rally front body mounts. I've seen that done before. This way you can still use the holes and have the front xo-1

    I believe we are on the same page, right now the tunnel bottoms are about 4.5mm off the ground, for the sides to fit in the tunnels the xo-1 towers are almost a must.
    Of course I still have a lot of room for adjustment with everything as nothing but mock ups have been done, I have not cut into the diffuser nor intend to, just shock limiters and other adjustments.
    Yes modifying the front diffuser for the stock mount holes is something I have also thought about
    I just got permission to use the local small town airport taxiway for speed runs, this will be perfect, nothing in the way and grass on both sides.
    I guess I'm getting a bit anxious, perhaps some trial and of course error runs are in order.
    Thanks for the input my friend.

    Just to make sure we're on same page this is how your rear diffuser is now

    And not like this with cutouts for the A arms.

    I can't see how it would work like that in the first pic unless you have spacers between the diffuser and rear bulkhead.
    The second pic is how I have my sons cut out the pic is another one for my second oldest son but I removed it. I also premounted my old pf8 body on my rally with strc towers and it sits pretty low but I didn't have the rear mounts on. I do run xo1 towers and shocks on both my sons rally. But only because their bodies wouldn't allow me to run the stock height towers and keep it low
    I guess some pics of how yours look might help.

    I have spacers between the rear bulk head.
    My diffuser is untouched just as it came brand new is how it remains.

    Here are the spacers, had to pull the tunnel down a bit for them to show.

    Oh wow. Haven't seen it done like that before. Awesome job there. So if you went with xo1 towers you'd have to find a way to use the existing holes. Which means modifying body post, or use the rear diffuser body mounts and make new holes. How much space is between your body and the side plates

    I've never seen that either. What did yiu use for spacers? Does it affect the rest of the diffusers? Got any pics of the whole underside?

    To much, this is why I need a plate like the one you made.
    If you mean the actual PF-8 body sides they fit decent into the side rails.
    Keep in mind I still have a lot of cutting to do on the body, also bring the tunnels up or go to XO-1 towers.
    I just realized its the inner tunnel holding the body up where the body curves at the bottom, if I trim them down I can keep the strc towers.

    Right now I'm using Hot Racing 3mm spacers, you can get them in packs of assorted sizes.
    Here are some pic of the under side.

    Please excuse the messy JB weld, still have to sand it down.

    Hmm I was able to slid my pf8 in and around the inner and outer tunnels and it stayed there.

    My inner tunnel was (where its tallest in the middle) hitting the body in this area, mainly right where the whit dot is.
    I didn't see it till I saw it was scratching the paint there
    [IMG][/IMG]
    After trimming this off it slides right down as well.
    [IMG][/IMG]
    White line I removed about 3/8"-1/4" of tunnel top.

    I tried epoxy on my side diffusers and eventually broke it. I ended up using a piece of metal to fix it and found out it would be the perfect reinforcement. One piece will hold the entire diffuser together.
    This will TOTALLY work, saw a guy on YouTube do it

    This is a good idea, I'm planning something along the same line after I get done sanding everything down

    Yeah I did something similar. I used the inner part tunnel that was cut off when making the modified ones. Hope that made sense lol. I then drilled holes and screwed it to the inner tunnel that you billy just shaved down

    How are you keeping this thing on the ground? Any extra weight? Did you go back to the aluminum chassis? What was the problem with it?

    I'm still having problems with staying on the ground.

    Trust me I had many times where it went flying. More then staying on the ground. No added weight, haven't went back to aluminum chassis. I had better luck with the jag body staying more on the ground last year. This year I have not once touched either of my trucks and I got the XLX when they came out lol nor has my boys drove them. I've thought about selling mine

    Cool. Well I'm a little disappointed that I couldn't deliver my 100 mph promise but at least I put on a show.
