I would say I have about 2/3's of the pin left. I'll leave it for another race or so. Those pins are pressed in right? So do you have to replace the whole CVD, or can you just replace the pin and press it in? Thanks alot guys for you responces

i'm using a nontuned grp 21 in my truck. the motor seems kinda flat. i recently put a new clutch on it but all i had was the stock alum and composite shoes with gold and green springs. i kow that the truck came with all alum shoes. could the composite shoes cause it to feel like it doesn't have that normal snap?

I have run modded GRP's tuned and non tuned and they all lack torque. You can help this by going to silver springs, but you will eat clutches. Put a 053 pipe and a long header that helps too. Or try a high torque pipe and long header. Thats all I got. The GRP's are always lacking in the torque department.

You should be good. There are tools that you can get to press the pins out and replace them. However usually the other end is pretty worn by the time that happens. I had probably 10-15 gallons on my origional 1.0 front shaft before I changed it. Don't ask me how, but it lasted for me. It seems to me that once they wear at first, they will hold up decently for a long time.

Thanks Jammin.....Hey frank L, my tuned GRP .21 is flat on bottom as well. If I put silver springs on new long wear losi shoes, in your opinion how many gallons (if that) would I get on the shoes? Right now Im running the green and gold springs on long wear losi shoes with about 3 or so gallons and to me they dont look very worn at all. I have'nt had to clean them up at all.

You will severly shorten the life of your shoes with silver springs. If that's all you can do to get bottom out of an engine, I guess you have to do it, but it will cost ya. That' s why I never liked GRP's. Not enough bottom for me.

i think what i will do is put the grp in my buggy and put the pico evo2 in the truggy. the pico had alittle too much bottom then i liked for a buggy. i will give it a shot and c how it works. worse comes to worse i will switch them back

i alreade run the 053 pipe on the grp.

With all silver I have gone through a set of lightened shoes in a 30 min main with all sliver, but the low end was helped out. You might get 1/2 gallon on them before they get to the 23.4mm measurement, but not much more. I switched to an OS speed and went with king headz 6061 2 green and 2 gold and they wear very very slow. I have over a gallon on this setup and the wear is minimal 24.3-24.4 hardly any wear at all. The speed has plenty of bottom, mid and top end. I love it.

Long header? and a dyn or ofna 053 not the GRP 2053. The GRP pipe is flat compared to the dyn or ofna 053.

That would be a VERY wise move. Those picco's have plenty of bottom end. IMO too much for a buggy, and great for a truggy.

Right on thanks Frank...I need my set up to last more than a half a gallon or so though,...so I'll just sacrifice a little bottom and keep grn and gld, and rely on the wicked top end these GRP'S have . See you at RiverFront

dyn with the header it came with

You could split the difference. IMO 4 KHZ 7075 shoes with 4 gold springs would be a step in the right direction, and still not kill the shoes.

I already have the new long wear losi shoes, so how about four gold with them, that might be a little better huh? And how often do you guys change out the springs? Is it just every time you replace the shoes,or do you reuse the springs. I have always replaced the springs since I have been doin this stuff the last 7 months, but didnt no if it was necessary.
