How did you set your drag brake? As in, what are you looking for from it?

Making the step up to Mod from stock, brakes are waaaay more effective, I'm more curious to find how much push brake you actually use and how much drag brake as well...(my spur gears thank you)

That's what I'm doing as well. It's fun, but VERY frustrating.

well,it didnt work,it smoked out today,went over to a gm and thats stuck at 60c with no change to gearing and its a bit faster

Hi. I have a couple different set ups for the XB4 at trackside. honestly i thought my car was best here with the stock set up with just a couple modifications. 500ft scock oil, 10,000 ft diff oil, lowest camber link hole on the rear shock tower, 2line progressive front springs and .5mms more rear toe. I havent really been able to run much lately do to other races and things. i know that the track seems to be changing a bit (getting hard) and people have been liking the pro line Ion's also, hopefully in a couple weeks i will be back to work on it.
As for tires right now i would say a M3 suburb (broke in) in the rear and i make my own fronts out of rears, otherwise you can use a scrub in the front. as for inserts the stock foam is the best right away but after many runs the closed cell will be better. the pro line closed cell will beak in pretty fast in rear tires, but fronts will take many more runs to break in (likely in to your second set of tires with those inserts). All in all i would say to use closed cell in the rear and stuff a full rear foam into the front.

I can help you better at the track when i can look at the car a bit.
Thanks



, Thanks!

I like more drag brake than most because im not that great at using push brake, I suppose what i am looking for is the proper amount of drag brake for the track, knowing it cant be perfect for every corner do to varying entry speeds and lifting points etc, so I know that in some corners i will lift and still have to stab a bit of push brake, but if tuned right at the majority of corners i can lift when i want and not have to use any push brake. It helps reduce another variable (braking) to driving and i feel it makes me more consistent.

hope that is what you were looking for.

Lol. I always use Max brake force in my speedo and my radio, this way i just barely touch the brake and the tires pretty much lock up. Again since i suck at using brakes i use push brake as emergency brake in a sence and give it the smallest stab whan i use it, by having the smallest of movement in to the brake side it again helps me be consistent BC their is no variable of how much brake you use, its pretty much on or off and your finger dosent have to have a great feel in the brake side of the trigger. This is not really normal for other pro drivers from what i have seen though.

The drag brake selected is dependent on variables un known, speedo, Gearing, timing, motor, rotor, track size, motor temp, track layout all will play a role. as with anything though just throw a moderate amount of drag brake at it, 10% is fine and start increasing it or decreasing it to see how you like it.
keep in mind though that more drag brake cam mean a ton more heat, so sometimes i am not able to use as much as i want in fear of things overheating.

Hey Paul,

Great thread, thanks for helping all of us.

Last weekend was the first onroad day at Leisure Hours and my first day with a T4. Last year I ran a T3 2012 car there in mod TC.

The T4 ran very well for the most part, and I had a decent day running 10.5 boosted but have one thing I would like to do away with.

At the end of the back straight going into the sweeper my car wiggles through the whole turn as it fights for grip if I enter the sweeper a bit too fast. This makes it hard to get back on power coming out of the turn because the car can snap out of control if I pick the trigger up too soon or hard.

I would love if the car smoothly pushed at the limit rather than this wiggle. I did notice one other car running mod having the same issue but I did't speak to him about it. He was on Solaris tires and I was on Sorex so I dont think it was my tires. I didn't see Jucha's car do it but noticed that he was taking a very wide line into the sweeper. Maybe I just need to get out to the edge of the track?

Any suggestions?

Track is medium grip asphalt.

Setup was your 2013 ROAR nats setup as a base but with:

2.5f/2.3r springs
400f/350r oil
3.0/2.0 droop ORH.
roll centers in middle all around
spool up front


Thanks

Paul L

Cool, Glad it worked well! Thanks


Hi Troy. Glad you got out their. I heard their were 2 heats of mod, Pretty cool!.

I would reduce your front droop to 2mm as well, then i would move my rear wing back 5mms. This should help the cause quite a bit. Good luck!

Thanks for the detailed answer, will try and put it to good use this weekend!!

Thanks, I'll give it a try! My rear wing is almost flush with the back of the body so I'm sure I have room to move it. WOW, now that I think about it last year I ran an LTCR all year but now I have a Speed6 on it that I ran inside this winter. Maybe I should switch back...

There were plenty of mod guys and I'll be back in mod next time out so I hope the class stays rolling. I ran 10.5 this time because I didn't see anyone committing to mod but it turned out to be the bigger class. I hope mod is epic this year at Leisure Hours.

Hi Paul,
One more quick question on the XB4. I see lots of people on the XB4 thread recommending weight be put under the batteries to help with rear traction. Do you run any weight under there? Thanks again!

Paul L

No Problem. I dont but i have not tested it yet. if you try it let us know .

Thanks

Paul L

Ill be back to catch up on here next Tuesday after the reedy race.
