Default C4 Front Spring Adjuster

I have vb&p Xtreme front spring. I need the longer spring height adjuster. I had an email from them once with who supplied theirs but can't seem to find it, and they no longer exist. Need to shift some weight around.

My spring has 5/8"-11

Thanks..

I also have this spring. Maybe off topic, but are you trying to get the height up higher? On my 88, the allen bolts are almost flush with the embedded nut, and i still need the front up a little higher. I was actually going to see if anyone else has this problem. Spring has been installed since 2008ish, and im just getting around to doing this. And it figures VBP is out of business.

Im sure a grade 5 or 8 bolt would work fine, but i dont know how the bolt is attached to the "puck". Ill get a pic of mine tonite, would love to see where yours is at also if you dont mind..

Thanks

I have the adjustment bolt flush with the top of the spring.. Reason I want the higher one, I want to move some of the weight back... This is with the 315/30R 18s on the front...

315/30R18

Thanks..Here is mine...
Do you drive on the street? Any issues with it this low? Like i said, i can go up a little more, just wanted to see someone elses ride height.
In my notes from way back, someone told me to jack car up if your going to lower car. He said the bolt can unscrew from the puck. So im sure you can go to Fastenal for longer bolts.
Thanks again!

Playing with street stocks where jacking bolts were illegal; shimming springs was required to get set up right. You could make a shim (s) out 1/8 - 1/4 inch plastic, delrin or similar; install it between "puck" and arm. Then readjust.

I was debating putting something between puck and a-arm......

If I'm reading your reason correctly, you're trying to bias more of the weight off the front tires and onto the rears? Raising front ride height or lowering rear ride height won't do that.

lol.. should have just asked you directly.. we cross everywhere, just not on the track yet, one of these days you will make it out to nationals in Lincoln...

but seeing the pic of his I see they are not all the same, mine is a single piece.. That piece looks like a Fairlane Female bumper with the stud in it. I will have to take a pic of mine so you can see the difference. They told me they got them from a few different sources.

Part of the reason, I also want to get the front up a little.. Tired of hitting every crack in the road.

We'll see how this year goes. I'm definitely doing the CAM Challenge in Peru again this year, if that is on your radar. I do get the road clearance reason for raising it. Also just in terms of compression travel in the suspension, it can be too low to allow much. Definitely don't want to be cornering on the bump stops!

On the topic of these VBP Xtreme front adjusters, mine are stuck due to rust. I'm afraid to put tons of pressure on them for fear of spinning the insert in the fiberglass. I'm going to try periodically hitting them with penetrant oil to see if I can free them. I guess antiseize is in order after that.

I was thinking Peru or Mineral wells this year, Peru is a bit closer.. Depends on the Car and life, they all seem to get in the way of racing..

Right, with VBP gone, the Xtreme springs are irreplaceable, hate to damage what you have..

You do tighten the bolts to raise the car correct? Sorry for the stupid question.

You would turn pucks down to raise car. If you are going to add shim(s) under puck. I would set car on blocks at approximate ride height. Back pucks off a little more than halfway then slide shims in. Then take a spin and recheck heights and scale it. Once ride height is where you want it, I would work with rear first to set weights. Then adjust front if you have to. If you're a large fellow, you may want to place ballast in driver's seat prior to setting weights.

Thought I would answer my own question, if anyone looks this up in the future, with the same question. You can get the bumpers in the above picture, and a thrust screws in different lengths at [img]data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAOoAA AAUCAYAAACDDKEnAAAD70lEQVR4nO1bPW/bMBC9NujWn9DBYzM1RUePnTokDbJ0DlIb6AccITD QpYCn/gYNWvoDvHcoYEBDgQL1okWDoKXQ1MF/oa8DJZtHUrKY2LGt3gMEOKT4SB/v3R1phCAQCPYa9PAFaNeLEAgEzSCiLgh1gWgyR3+ 64M1Zjv4wQZTtZlUCwabgKVQliCDe3oJuhRpB5tM ENMmR72ZVAsHGQHS8SaG6+rcv7nyagMKixVoEvpi FjkpFcO/YcEbdhVBr+LMc/WGK2bam/U8gQt0P3FKoBYLhHDScg5Zi0NvmoGGCKHO1AYhTU FioTFj16RkxTu0xUE5jlbI1gmRZNk75OKtUrs64v y3Rz0LX2lLMWnPaTp5PE/SnC8Vdfs8gBrMHH6e4zD5vnixHf8jfZfZie8rnZO +z/dF5FogmCaK4mqcmULJ12Dbj69DGTHLk+txhwbk6f MwJ6NJfqCsDln8vHbllRi2NvXIiJWj1ToGg5gJIO STf/HZlr8EZp+hPEmN+1c/5FojChAWCVX97ThOVKKr1LUWiBxYzQDEbq/X48RQIdNtVAQdorD6sjGoGJJ3H8g8X9L0u+cICti 8ZgbkSZNWfmcFA8XY1+9+59OUXNh5CNaLfyhl9DG 5sus7PnIVnt1lYRn1XxjUdOCzU+5n5XTw4DVjBxR JKu8Dlx2NAF1zp9K73TKHagdG2SeMxp84urmBhrd He08bqp0O4+xmVGf72QuUOoJXMTYa3BKng2rAV/wJRmCPXMgx3Rk0YcbosJfvTheUs7Tk5vATW8BOTt 1CNkpWVnVoJqa/b/B56mW2Xv+uFWnsT79xLbS9EqPshVLeRm7OrWww1G aja6GyV9WbhHEFcnqu09yveZSbVz0cuYbTg1LGTj GoKvi4AGNl1fUbVIRl1W9iKUF0XIazNPKPWll58P n6ZVOPAtSVnyRWm/DImTJUILY4UwUQ//6QIwpogtI7T+H5+QnXdA2hn1LY8RsZS51lXAOB2d V+m1QUht1BdZ037jGoHZXucCLUl1mfH1e3hajOtt nJMpJVRpmhdt8HsMqlGkGtLTke5587KDXP7ct5Jq Np6HLe+PjysbA1TVuKTgx/gfetL6BZCtcbrojd+JbCCnQj1ftFw0dIWXmWvQHD gOFCh+pa9AsFh48/Vr/ZCdd32ySPPvj1dREf+e0Yg6DZEqALBAeANfRahCg T7DiICXdJbjCnADQ1Ugzwdex6A6Kj8fISvwTdkP0 6Bn9/x5f3fsv0JiB6Xnx/hFZ1hTCN8pAEu6Cl6dIwLOsczeo0Teo4TOsE59dC jUwzoDJ9ojBu6Ro8+4JpeYkQjXNEA72iMEV3vgQ0 O//kHcZi7JZuT3jQAAAAASUVORK5CYII=[/img] .

If you can't get any help with VBP parts call Van Steel in Florida. They seem to have a lot of the parts that VBP used to sell.

If nothing else they are very well versed on the suspension of most generations of Corvettes and they do awesome work as well.

Good Luck!

Is it me or is that link not working?
Id love to get longer bolts instead of shimming. Mine are bottomed out, and you can barely get a finger between front tire and hood (fender lip)

Thanks
