When that happens, I try to tighten the front diff more... That's what I'll do. Fast, quick and easy. Try and see what happens until you get the right balance.

I actually try to run as tight a front diff as I can to get the car to be very stable throttling out of the corners.

Are the bumps avoidable? Sometimes I think setting the car for just that few bumps is not worth after all. Better to take different driving lines to avoid it (if you can) and set the car up for flat and smooth traction. That's my take.

That is correct. So driving skill and throttle control comes into play. In the end, it all boils down to driving style. Some people set the car up with so much steering and control how the car behave on the track with their hands. Some people set their car up so much so that whatever you do, it'll never upset the car ! That's fine too but you won't see any "magic" moments when the car is driven to the edge in a race.

You'll definitely have this problem when the front diff is set lighter than the rear diff. Always try and set the front diff relatively tighter than the rear. It'll make the car more stable on throttle out of the corners.

Yes it would. I suggest more open holes with 35wt or 40wt Serpent shock oil. I think that's about the best for the car. Makes the car react very fast and stable in the corners. If you have the older 1.0mm shock pistons (how old is your car?), try 4 or 5 holes open in front and rear.

Unfortunately, the bumps are not avoidable. I will try setting the car up with a little less droop and see if it works. I do notice more body roll than normal.

My definition of a "magic" moment is when I actually finish a race at the Fort.

I will give the front a couple of turns. It's hard to know how tight it is. What may seem tight to me may be loose to someone else.

The car is not that old... maybe 8 months. I also have a few new shocks kits. How can you tell the difference? I have always run 3 holes. I guess it's time to play with them.

As I have stated before, I have never deviated much from the "stock" setup before because I didn't know what I was doing. Now with all this help it's very exciting.

Thanks,
jag

Oh yes ! I believe he raced there some time ago but that should give you an indication about his age. I believe if you search the sgrid forum, you would find a posting from Julius on how to drive around the Ft Myers track. I think he posted it here too but I can't seem to find it.
The reason I was asking about Ft. Meyers is that's one of the tracks in my state race series. I was wondering if this setup I am currently working on would be good for that track? Most of the "fast" guys are using a front one-way. That track is much faster and more open than the track I run on locally.

I don't mind if Julius is old. I have learned many things from old guys. I'm not young either. I am a firm believer that you are only as old as you feel. That's why I play with toy cars.

I would stay with a diff, the front one-way is very hard use when braking, and the car will be more tricky, it's more for the experienced driver i gues...

Default Clutch Mod

I know that this has been discussed multiple times, but I cant find any pictures of the flyweight mod.
Could anybody (InitalD?) PLEASE post a pic with a cut clutch shoe placed as flyweights between the pins of the flywheel?


Many many thanks in advance!!

There has been mention of rear roll centers, so I had a look at mine and found it was as low as it could go, so have gone with Julius's recommendation, which seems to be the same as Initial D's if I understand correctly. The lovely Serpent setup book says to increase rear roll center to get more initial turn in. Will give it a try this weekend.

In regards to shock pistons:
I've been seeing posting about a 1.2 mm hole piston. Is this a mod people have been doing, or a piston I should look into getting? If someone has a part number please post it so I can get them.

Thanks in advance.

What this with my age all of a sudden?
I did run Ft Meyers but that was with a 2WD 235 car back in the previous century..... (Talk about Old...)

You may want to look for Michael's setup from this years race at the Ft. Things changed with surface they put up there last year.

A few pages back Julius told me to try my rear roll center like this:

Lower - upper
Upper - inside middle

I don't know if Initial D runs his the same way.

I doubt you are any older than I am. Although I didn't know they ever made 2wd 235mm cars. Do you drive with a stick radio?

Why don't you come over for the WinterNats this year. I could be your pitmonkey... or you could be mine

I will check MS's setup.

Thanks,
jag
