Ground Control Group deal

[WRAITH]

Dear All,
There is a Ground Control group deal going on in the SER list. Please contact Melvyn at [email protected] for more information.

A little bit about GC... I sat in George's G20 with 375/ 275(correct me if I am wrong, Geo), the ride is firm not hrash... Very German like kind of ride. However, I have not try out the new spring rates George has on his car now, which something like 275/225???

Bottomline is, I will not hestiate to get GC if the price is good. I believe such approach is better than just normal lowering springs.

When you rode in the car it had 340/275 springs. I am now running on 275/200. I think I would like to try 275/225 or 300/225. I think I have the car a little too low currently for the 275 springs up front.

If you liked the 340/275, I think you will really like the 275/200. At 340/275 I thought it was a bit too jiggly for my tastes and certainly Kerry's. I think the 275/200 rides incredibly well and I think the only place you would notice a difference in handling is on the race track. If I were to do it again, I might try 300/225, but until I have the opportunity to raise it a little (about a quarter to a half inch - .5-1 cm) and change to Koni bumpstops, it's too soon to say.

I also think if I were to run Konis I would be much happier - especially at higher spring rates due to better damper tuning (I believe Japanese dampers have too much bounce and not enough rebound damping).

I called the vendor Isidro at High Performance Online 1-800-868-7174 today and he gave me a quote of $444 w/o shipping. This includes 4 GC coilover springs and 2 Front GC camber plates. The rates that were recommended to him by GC were 300f/200r. He says he sold 7 sets already to P10 customers and is currently all out, but Ground Control is providing more sets for him in the next couple of days. This deal is only till the end of the week according to him. Just passing the info.

He's quoting you information for a SE-R. His cost for G20 GCs and the CC plates is higher than that. I know what dealer cost is on those products.

The G20 set-up costs $100 extra due to the front mounting plate that comes with it.

If he is selling you caster/camber plates for a G20 he is ripping you off since they won't do squat for a G20. Are you sure he is aware you are talking about a G20?

Ground Control recommends 340/250 for the G20. How do I know this? I organized a group deal for GCs and talked with the folks at GC directly. I also know that they recommend 300/200 for the SE-R.

That said, 300/225 might not be a bad combo. I originally ordered 340/275 and switched to 275/200. I think 300/225 might be a pretty good set-up. You cannot run it quite as low because of the lower spring rates, but it's much less giggly.

Don't go for any deal that includes the CC plates for a G20. They won't do a thing.

Just got a call back from Isidro, the P10 setup DOES NOT include the front camber plates and the spring rates he quoted were for a b13 but he did know I was asking for a P10. He called Ground Control and they recommended a spring rate of 340/250 as Geo stated. He says the price is still $444..sorry I'll pass. Oh well...

Yeah, that's what I thought. Isidro is a pretty sharp guy.

That price makes sense now. As I said, the G20 applications come with a machine (and anodized) plate in the front that replaces the stock upper spring perch.

If you're adventurous, you could run some lower springs rates. I really like the 275/200. If I were to do it again, I'd probably consider selecting 300/250, but I wouldn't recommend this to someone else. If you're adventerous, you might try 300/225.

I'm not recommending those rates, but if you want to try something different, it would give you a little better ride. Keep in mind you cannot lower the car as much with the lower rates as you will be more likely to bottom out.

Well, now that I have taken a long trip in My car ( 1993) I think I will try ground controls. For a short ride to work or the gym , the " jiggles " are not bad. For the ride to Orlando (3-4 hours) it is way to much ... there is even " jiggle" on the high way on place where I never new they was a crease in the road . It made my cd skip !!!!

George, I have the AGX's. What Ground Control Settings should I get. I do not take my car to the track. I just want it to still look nice and lowered but lose the jiggles.... I know I can not have stock ride but I ride closer to my 91 stock car or A BMW 3 series... those cars are firm but no " BANG ! " and Jiggle ....

Well, I still recommend 300/225 or275/200. The lower spring rates will not allow you to lower the car so much but they will eliminate more "jiggliness." However far you lower your car, don't lower it so much that it hits the bump stops. That is was causes a lot of harshness with lowered cars.

So how low is the rate you recommended 1.3 -1.5 inches... I think I am lowered like 1.75 now it look nice but I am willing to raise up to kill the jiggles and the BUMP STOP banging ....

I also think I should move up to the 215/45/17 tires ...

I'm running 205/40-17 and have the fender lip just a bit above the top of the tire. I think I'm going to raise it up 0.25-0.50". Probably closer to 0.25". I think that would look better anyway. I'm just barely hitting the bump stops. Raising it 0.25" and installing Koni/Truechoice bump stops should get rid of the last bit of harshness over big bumps I think.

Which shocks are you running again now... and where do I get those Koni/ Truechoice bump stops ..

I'm running AGX, but that's because I got them barely used for stupid cheap. Otherwise, I'd have Konis. I was working out a Koni solution when the AGX were offered to me. I think I'll eventually end up with Konis, but cannot justify the expense right now. Down the road a bit.

You can get the bumpstops from Truechoice. Do a search. They are on the web.
