KilRuf-

Craigs car had the Low Roll Center on it and he used the regular Diff's. Droop was probably 3 in front and 5 in rear. I think that is what I heard him say.

The MF bumper brace is a pos. I would buy a piece of kydex or cf and use your MF bumper brace as a template to make one that won't snap in half with your first mild impact. As the brace fits flush against the front bulkhead, I don't think you need to worry about sheering off the alum bolts, but I twisted the head off of one when backing it out. I replaced mine with Dubro steel bolts and a washer to spread the load around.

Sway bar angles?

Mark D, do you know if sway bars are suppose to be level with the chassis or not? I just finished customizing some sway bars for the xxx-s but the front bar is a little nosed-down. If so, what effect will it have on the car? Thanx- Jesse

psycho-

How did you snap the MF Bumper Brace? I have had multiple front end colissions and some were very hard but all is fine with my bumper.

I broke my aluminum screws on my MF brace after a hard hit. I suggest using steel screws. I just let mine float now and it seems to work fine that way.

I don't remember exactly what happened, but the crash caused the brace to snap along the left edge of the milled out "M" up to the left screw hole. I've seen several other broken braces that looked just like mine. This is wheer there is the least amount of material, so it makes sense that the break would occur here. I am using the stock foam bumper, which isn't very sturdy, so maybe the impact flexed the foam bumper and contributed. I think the MF brace would be stronger if they didn't mill out the letters in the middle.

Default Bumper braces

A couple of posts back I warned everybody to use a solid bumper brace.
Ottoman, if you used steel screws your whole fron bulkhead cap would have been most likely ripped off, just like mine did.

Look at Spashett's car from Cleveland. Why do you think he used a flexible Lexan brace?

I made the holes, where my brace connects to the bulkhead big enough to insert rubber grommets (hardware store, cheap)
I use large washers on my screws and don't tighten them beyond snug.
Since then I haven't had any problems.

Anyone have pics of the amount of material that needs to be shaved off to use the Integy (or MF) low-rollcenter blocks?

Thanks

I don't remember offhand as far as lengths go, but for the droop screws you can get away with just cutting the kit ones in half -- that's what I did. I couldn't find any droop screws in the correct size/length at my LHS so I just busted out the Dremel (again).

As for how much to shave off the chassis to use the blocks, just do it bit-by-bit and test fit the parts each time. You want the low-roll blocks to sit perfectly flush (horizontal) with the chassis, otherwise you'll be throwing off the kick-up angle. You shouldn't have to shave off too much.

For the bump-stops on the front and rear bumpers, just use a cutting wheel on the Dremel and cut the stops off so that they are flush with the rest of the bumper's surface. You should be fine with that.

They don't rate them in pounds. Yellow they call .70, Purple .65 and Blue .60. I hope that helps. I've directly compared Losi purple and Trinty purple. The Trinity are slightly stiffer.

Ask Larry D. on Trinity Tech Talk. He once gave the Congo spring ratings but I didn't write them down.

alright experts, gotta question for you.

Currently running Paul L's carpet setup for rubber tires with the exception of 2 degree casters (he ran 4) and green springs front/blue rear.

My question is this:

My turn-in is good but I am still having a probem with a little bit on power push on the tight turns. My current tire setup is Pit 24 (jb foams firm) up front and sorex 20 (yok 26mm firm) in rear.


Any ideas?
