They don't make the radial version in that size or I would probably get those.

I had to beat the living hell out of my inner wheel wells to get the 325/50/15 to fit. The pictures in post #5 of this thread were major time savers: https://ls1tech.com/forums/drag-raci...5-50-15-s.html
About your vibration... just a question... what material transmission and motor mounts do you use? I had poly motor and poly trans and my vibration was ridiculous. I could NOT for the life of me figure out what was causing it. Threw money at it left and right... driveshaft, converter, tires, wheels, flexplate. Nothing worked. Finally, getting rid of the poly transmission mount and replacing it with a rubber oem one resolved the issue. A stupid 15 dollar part. Sometimes it's the simplest things, huh? Don't know what your setup is, but just thought I'd throw that out there. Hope you figure it out. Have always loved your car. Good luck with it!

Whats the difference in the et street r's compared to the original et street radial 1s besides the tread pattern? is that why they dont offer them in a 275/60? Maybe go with the et street radial pros if youre not gonna daily on them?

I have clearanced for the 295/55/15's already by cutting bump stops out and hammering a bit. Wondering if I should just slap some Pro's on it and call it a day though.

It has solid motor mounts and a poly trans mount.

Thanks for the help and kind words.

Totally unrelated and sorry to ***** the thread, but on your solid motor mounts did you locktite the bolts that go into the motor? I've got spohn mounts on this new car and noticed yesterday while under it that a bolt had backed out. Kinda made me wonder maybe the previous owner shouldve used something - locktite or washer - to hold the bolts in better?

The Pro's and the regular street radials are the same compound but the reduced pattern makes it hook better obviously. The et street r's have the pro pattern with grooves to be more street friendly are approved for street use, not that it really matters. I don't DD the car of course, but do drive it a lot. I have some stock 16" wheels I can run on the rears for long distance travels but I live 20-25 miles from Des Moines (where all the action is, lol) and easily put over 100 miles on the car when I make a trip there and back.

If money were no object then I'd have a different set of rear wheels and change them out depending on what I was going to do that day/night. 555r's for DD'ing and cruising around, ET Street Radial R or Pro for the track, and Hoosiers or ET Drags for street digs and some track events.


Don't worry about whoring up the thread. If anything may help me or someone else feel free to ask/post whatever. I can't remember if the motor mount bolts were put in with locktite or not. It's been so long since they were installed. I think that was the only thing I didn't look at last night while under the car. I will do that this weekend when we get it back on the lift.

I talked to mt about the radial r and the pro
They're so close that they didn't have a need to produce the radial r in a 275/60

Glad to see you have the car back Andy, any changes planned for it?

RedRocketZ28

iTrader: (19)

Not a whole lot of changes planned. I added the 2-step and will probably put some Viking shocks on the rear eventually. I want to clean up the engine bay a bit as far as wiring goes. I may get an ABS delete kit and line lock for it as well over the winter. Other than that I just plan on driving it and having fun.

I planned on building something really similar to this after I sold your old 2000ss
Just couldn't bring myself to start cutting up such a nice car
Ended up doing a turbo setup on my Gto and I'm just not that happy with it, the car just doesn't work as well at the drag strip. Makes a **** load of power, just can't get it to go down the track
Might pick up a cheap roller soon and try again...lol
What kind of times/power did it make with the old cheap turbo on here?

I wasn't able to make a clean pass the ET Street Rs yet as I had a ton a problems and ended up putting the car on the trailer.

Buddy with a TT GTO went 1.3x on them. The Pro'ss are badass tire, and I heard the same thing you did about the ET Street R, it is basically a Pro. I love the look of a 325 on my car that is why I went with them.

I have had the Pro on my car and I went 1.31 and 1.30 with them on 8-10lbs of boost on the line.

The Pro's and the ET Street R feel like they have the same sidewall construction and very forgiving when trying to get them on beadlocked rims.

RedRocketZ28

iTrader: (19)

I just now realized you were the one who bought my old SS, ha. Your GTO looks like a beast for sure.

With the on3 turbo it made 606/570 on 14 lbs. Switched to the Turbonetics 7875 and made 677 on 16 lbs. (can't remember tq figure off hand) and went 9.92 @ 140 on 14-15 lbs. That turbo had more in it but power dropped off around 5700 pretty hard. When I switched to the S480 I also went to a 3.00 gear out back and it just never seemed to like it. The previous owner went 9.96 @ 142 on a stock 80e that was on its way out and that was on 16-17 lbs. if I recall. On that same setting it made 730 rwhp. It now has a 3.50 gear and a triple disc converter. I plan on getting it to the track on 10/17 and leaning on it pretty hard in the 1/8th at least. Without a cage I am leery about running it out the full 1/4 anymore. Cage may be in the works over the winter depending on funds.

Thanks for the info. I am somewhat worried about the 325's on a Camaro since they fender wells aren't as big. I don't want them to stick out and look ridiculous. Not to mention the racestar wheels are a 7.25" backspace instead of 7.5", which I am not sure would be THAT big of a deal. I need to make a decision shortly though so I have something in time for the track outing.

So I had some time this weekend to get the car down to the WS6store to put it on the lift again. We swapped driveshafts, took it for a quick spin, and the vibration was pretty much gone. We went back, swapped in a stock rubber trans mount, and all seems to be well. It used to rattle your teeth out around 70-75 mph and now it's nice and smooth. I still get a slight, barely noticeable vibration at times, but it is basically non-existent compared to what it was. Pinion angle is at -1 currently and we didn't mess with it anymore.

On another note, I am going to order the MT ET Pro's instead of going with the ET Street R in the 325. Also need to get a new wideband sensor as this one took a dump and only reads for a few minutes then shows maxed out at 22.4. I had problems with the Innovate MTX-L before and may just end up switching to an AEM unit. I think I will also get an AEM fuel pressure gauge to replace the Glow Shift one that's in there now so all the gauges match the AEM boost controller. The Glow Shift gauge works just fine but I want to be able to log fuel pressure in HPTuners as well.

PLX wideband is the way to go! Not one issue in 3 years with it.

Did this today on 15-16 lbs.

Had an issue with the oil feed leaking a bit. Only made two passes and this was the 2nd. Called it a day after this. The old 03 LQ4 is still hanging in there.

Good looking car man and a great pass!

Thank you.


Looking at the video you can see the *** end raise up when I get on the 2-step. Obviously one disadvantage of foot braking and the way it unloads the suspension. Is there anything I can do to combat this and is that hurting the 60' at all? Would like to see some 1.3X's out of it if possible. The 2-step was set at 3400 or so and not sure I can get it up much higher but will certainly attempt to next year.

Glad to see you got the car back! Running well too, nice times and mph. It leaves so soft.

RedRocketZ28

iTrader: (19)

Yeah it does leave soft. Wish I could get it to leave a little harder but not sure I'll be able to without a brake. Need to play with the tune a bit next year and see what happens.

Going to add a few things to the car this winter. Going to start by getting a cage installed. Not sure which direction I want to go just yet but it will either be a MWC or Wolfe cage. Will probably throw some Viking rear shocks on to replace the cheap comp ones on it now. Also, going to clean up the engine bay a little paint and wiring wise. Not sure what else I will be able to swing this winter after that. Next spring I need to work on the tune a little to see if I can get it to leave harder as well.
