Ground control question

[onedayjake]

I got the ground control coilovers from T3 and have the perches cut off of my 280ZX struts. I'm getting ready to weld on the coilover perches and was wondering where on the strut housing those of you that have them have put them. I was thinking I should have the top of the sleeve at the top of the strut, but it seems it may put the sleeve too low. Any suggestions?

 

Also, I got KYB AGX for the front of an 89 MR2 and they fit perfect in the 280ZX strut housings with no need to shorten them! I'm hoping the Mustang rears I got fit.

You actually WANT to shorten them... otherwise you just wasted a bunch of money... (my opinion). By shortening them you increase you keep you get to lower the car, and retain some useable suspension travel... unless your going less than 2" from stock.

 

Once you shorten them you set the coilovers on so that the spring is at the top of its adjustment on the coilover sleeve, and pushed against the tophat at the top of the strut...

Thanks for the reply. I'm not going to go very low, I mainly wanted coilovers to be able to adjust spring rates easily as I want to do some auto crossing.

I did a similar query not long ago when i did mine. The general consensus was to put the top of the sleeve at or just below the top of the strut. Mine is flush with the top, and I have plenty of up/down movement. For me it worked out to be ideal. If I were to adjust the coils down to the bottom my car would literally be on the ground, yet if I went to the top it would probably be at stock height or higher.

If your going to autocross seriously enough that you have to worry about changing spring rates, then your choice in strut inserts is poor.

 

Also if your going autocrossing that seriously, you've got some real thinking on rear spring rates... which is way harder to figure on a 510 than most cars, and much harder to find high enough rates.

I beg to differ on hard to find spring rates! Circle track catalogs have everything you need! True, you'll have to cut the closed end off, but for 40 bucks a coil and good coils at that, it's pretty easy. I'm running SSS springs on my rears. (Suspension Spring Specialists) Day Motorsports or Coleman Racing both have excellent catalogs and a lot of things that can be put onto a 510 regardless of if it was designed for it! :D

Good info! So I pass to you this, how often to you plan with your spring rates (probably more often since you are doing rally rather than autox... no?)

What would be your choice for an adjustable front strut and rear shock? I'm on a budget like everyone else. Springs are available to me locally for cheap.

well budget is a big limiting factor... taking it out of the equation makes it easy. Tokico HTS or Koni D

 

Dont get me wrong, the AGX is a decent insert, but just not up to the task of heavy autox... (opinion, others may not agree, but I stand by this statement)
