Drag suspension

I recently lowered my car and have been having real bad wheel spin issues off the line. I ordered some parts to correct pinion angle and lower control arm angle but those won't be in for a while and I have some heads up grudge matches to race in before they get here. Could putting my factory rear springs back in the car help with getting my control arms and pinion angle back so I don't spin so bad? May be a dumb idea but I'm still trying to learn all the workings of the suspension and I don't know on this one.

You got to have the lca brackets to lower the lca's. Then you'll get the
traction back, the upper control arm will adjust the pinion angle.

I have those parts ordered from UPR, they just wont get here in time for me to install them before my track day. I was hoping that throwing the rear end back up would correct pinion and control arm angle temporarily.

That's what I did when I ran street ET on Saturday. I couldn't hook so I figured since it was bracket I would just be easy on the gas and consistency shouldn't be too hard. Dialed my slowest time ever, a 14 flat. Got into the finals after a 14.033 on my first pass, then I must have gotten excited cuz I ran a 13.7xx on my next pass ending the day for me. I still had allot of fun and that's what counts but it was getting aggravated over the times I was putting down... I'll get it next time.

You didn't mention what year your car is and what mods it has. But it looks like you already ran it.

I thought I would bump this instead of start a new thread. To pick up where we left off, my car is a 2012 V6 auto. I have a short ram intake, muffler delete, 3.73 gears, DSS aluminum drive shaft, SR springs, aluminum pan hard bar, and Bama hybrid tune for performance mods. That was the set up when I had my bad day of 14's... Easily the slowest the car had ever run.

Since this I have installed LCA relocation brackets (thank you UPR) and my times have came back down to a 13.5-13.7... I still feel I'm not getting everything I can out of the car and wheel spin is still killing my 60' times. I think the biggest issue now is my rear tires. I have 235/40?/17 pilot sports now and despite them being new I still can't get them to hook... Am I fighting a pointless battle trying to get these tires to hook up? I recently began working for myself so I don't have the money to throw around like I used to until I get my business rolling. So I was trying to remedy this without having to spent 600+ on wheels and tires because I just can't spend that kind of cash on my toys at the moment. I have been all over Craig's list and race junk but no love. I was hoping that maybe someone would read this and have an idea of what I could do to help get the power down...

Another option I have considered is removing the rear lowering springs and putting the stock ones back in. Some guys had mentioned it might help with weight transfer but honestly, that's a little over my head and I'm not sure if they knew what they were talking about or mad that I just beat there 5.0 fox.

Thanks,
TX

Like you say, you need gripping tires. See how expensive Kumho's are
if they come in your size. Remember to burnout a few times to get the
tires broke-in.

I guess I will have to save up over the next few weeks and try to get some wide wheels for cheap somewhere. Lightly used tires can usually be found for cheap around Orlando, I know a guy who buys smashed sports cars for his junk yard, maybe he has something hidden away.

what do you think about the rear spring idea? Its easy enough to swap out rear springs on these cars.... maybe its a dumb idea, but thats why im asking lol

thanks all
