I really enjoy your videos I have learned huge amounts from them I'm having problems with a new phone rack that I've started to go to So I'm watching them again lol Thanks again great videos
Glad I found this. This is brilliant. Rob has personally helped me with projects and he knows his stuff! If you want to get down the track, soak all of this up! These videos are highly informative! Rob can save you money and make your current setup far more effective! Liking, commenting and sharing this! Thanks Robbie!
Rob I love this video. I got a 15 second 78 Malibu. No real power, junk motor, but when I did what you mentioned to my factory 4 link the car became ET deadly, because it would 60ft the same all day long. If it 60ft's it will ET, and you can dial it HARD. That was 30 years ago, it still applies. I got 2 Chevy Monza's, the torque arm works, hope I can find the t-arm segment, I want to back half the monza's with bigger tire, but want to keep the torque arm, if possible. I'm, going to watch the video again now.
I have spent a ton of time reading about this subject and your explanation of it clears up so much confusion. Straight to the point, and that illustration with the bars taught me more than any conversation where all they talked about IC, AS, etc etc etc. Great stuff.
So helpful! I'm currently on the floor of my shop making some changes since our race last weekend at Bradenton to try tomorrow at Shadyside. Hopefully I'm making changes in the right direction!
TEMPTRESS RACING I’m going to continue the series as far I can go without getting extremely in depth. There’s plenty of in depth information out there. Just trying get everyone familiar with the terminology and which general direction to go in.
Glad you started this channel Rob. We've never been personally Introduced. But I see you alot at the track every Thursday night that I'm there. An you do help alot of people out. You seem to be a great guy. An good to see you helping out as many as you do. Im wanting to go to a 315 radial tire. Because it seems to be much faster because it dead hooks an every rotation is forward movement. But these slicks been giving us hell since we've actually put some power in the motor. Next time I see you I'll introduce myself. Wouldnt mind hearing your opinion on what you'd do to get our 60 back an ET
Joseph Lay slicks are finicky, weak, pieces of shit in my opinion. “Oh, yea, but rob, no prep” Yea to hell with that shit too. They have their place but they are so temperamental that they will not be on anything that I intend to race on a regular basis. Either way. Thanks for the support and I’ll be glad to help.
@@RobD828 hell with no prep too if gonna run like that. It will have the 29.5 17.50s under it an go to the street lol. Man seriously though after reading you comment that's what the problem was. We ran 1 no prep ever. And changed set up just a little and then never got it back where it was. But changed that again and got it back where it was an now it's back Atleast in the 1 teens in the 60. But I'd still like to go to a radial. Gonna have to throw these on an try them just see how they do. An well deff have to talk when I see Ya. Thanks for offering to help bud prob take Ya up on that when wear these junk tires out lol
Thank you for the info Rob! Any way you could do a vid on instant center length and height now? And when/where you'd want to have it longer/shorter/higher/lower? 😁
Rob, I can't tell you how much I appreciate you making this video. I've been searching the net for some advice on how to get my El Camino to hook up. I really do appreciate this
Guys like you make me wanna get Into racing for sure even on a small level. Just amateur 9or10sec class etc street care takeover stuff. I wonder if I can run an airbag suspension on the track or will I have problems
Hello, great video. I understand what you are explaining here, raising the pivot point of the lower linkbto push the drive angle over the top, forcing the front end down. I feel as though I'm finally grasping "the magic" that you've been explaining. My question is, A) How does this relate to the instant center (which is short, the way you have it shown here) and how close to the front bumper do you want it, especially when talking about either bagged or regular rear suspension (if there is a difference) and B) What percentage of "relief" (20, 30, 40, 80%?) are wheelie bars supposed to give in finding the balance between squat and driving over the top to keep the front end down? My problem is that one questions answer tends to give me five more questions and I sometimes over-think the whole thing but, id rather ask too much than not enough. This is mostly 5o let you know on what track my thought train is traveling. I try to get that dancing fairy stuck to the head of the pin, it just doesn't always happen... lol Thanks for the info.
Have a grand national 500 hp. Would like to get into setting my rear up using this method for the street or track. I have an all Hotchkis set up but all non adjustable. Can just adding new lower brackets and adjustable upper and lowers get my anti squat and instant center where it needs to be. Like the kit from UMI. I think it has 3 adjustment holes. Thanks for the videos.
Is your depiction of the center-of-gravity realistic? I was surprised to see it depicted so far forward. I really expected modern racecars to have the COG much farther rearward?
Most of our radial cars have a 60% + nose weight. I’d say if anything it’s further forward now than it ever has been unless you have an all aluminum nitrous small block in which case you’ll be adding tons of nose weight anyway
I think the dislikes are from Jackstand Jimmy and his ex girlfriends cousin sister Two Ton Tina But thanks for the explanation I had no idea what people meant when they said separation
What if we have equal length four links which should a more a gradual rotation at the rear end with less strain at the driveshaft in the universal joint ?? Less breakage??
Hey there Rob, great vid bud thx for that. In relation to a standard triangulate link setup with no pivot point adjustments, I guess you really can't afford to have the rear of the car too low , can bar lengths and pinion angle help here?
In my opinion it’s best in this situation to put lower control arm brackets on the rearend and move the down as far as possible back ther and then lower the car as far as possible.
I had to get my trq box’s redone a while back because my Fox’s factory trq box’s we’re destroyed due to all the abuse. I went with the kit from wild rides racing and I haven’t had any luck yet I know the parts are great it’s me. I’m not a wealthy man by any means but I’ve managed to put together a coyote swap fox gt and my only trip to the track I managed no better than 1.7’s smh on a 26 inch drag radial. I also busted a new tko 600 so I had a bad day my only clean pass I blew the tires off leaving at 4500. So I know my pinion angle is off. I have solid uppers and lowers but that trq box kit has multiple places. I just wanna go 1.4-1.5’s with a 430hp 2700# car. Yet I’m a second away due to the sus, gear and tire.
What tuning tips can you give for a street only car on radials? I have a g body and was thinking of running some southside bars on the lower arms. Strictly a street car never plan on taking it to the track
Please do a video on torque arm setup!!! I can't find any video on setting up lower control arms, torque arm, pinion angle, and shocks! Please help all the f-body guys out!
Can you clear up a pinion angle question. Does pinion angle alone, affect traction at all? Meaning, if everything else is right but the pinion angle is off a few degrees, would you gain traction by adjusting the pinion angle?
@@RobD828 Z1 Motorsports(Nissan Z and Infiniti) is one of the largest businesses for my platform. I'd imagine they easily have the means to producing kits. There just aren't many of us who are serious about drag racing them.
Awesome video. I'm looking for some tips on triangulated 4 link on top bar lengths. Does one measure the 70% of lower bar length the same way as the parallel routhe before mounting the top bar? I've searched every single corner of google on more info on triangulated 4 ling top bar length. Hope someone can help me out with some info.
On a four link with air bags, the angle of the top like and the angle of the bottom link (draw a line through both) should intersect at about the front bumper. This is the "instant center" and should keep the balance forward to the right point. Hope that helps.
Does this same theory apply to lower power cars running slicks? My car tries to stand on its bumper if I'm not careful. And at the same time it seems like it is wadding the sidewall like a top fuel car. This is in a 2700 pound car with a parallel 4 link, and 800-ish horsepower. 49% rear 51% nose. 99 inch wheel base. Thanks!!!
It does not. Slicks don’t like being crushed and you have to apply enough power quickly to keep them round or they will in fact wad up. I suggest moving to a radial as quickly as possible.
I'll have to disagree with the definition of Cg. Center of gravity is the point where if you held the car by that point it could be rotated in any position and it would remain in that position.
Any solution for the gbody stock suspension stuff? Only adjustment I have is on the lower control arm brackets on the rear end(4 holes). Will be running either a 275 radial or a 28x10.5w
@@RobD828 rob goss. Also Marty stinnett small block rvw/pro275 car squats. Both southern speed racing cars. It’s all in setup. When the bars aren’t equal length the IC grows so when you have too much separation they can get wheelie happy from that as well
@@SpeedProductions I think you need to research things a little further. Also keep in mind that the rear staying in the same location and the front rising is not the same the rear dropping which is what I would consider squat. Also please watch my shock video where I say “If the track is perfect I think you could take the coil overs out and just put solid bars in there place and do the same thing.” If the rearend isn’t moving this essentially what is happening. And you are correct with equal length bars growing.
@@RobD828 man I was just letting you know there is more than one way to skin a cat lol. I have seen the data from both cars and they both squat 1-1.5” as they progress down track.
