I have fe5 arms on the way along with drilled and slotted rotors. I have eibachs all the way arround with Koni yellows in the front and they are not cutting it.
I am looking at the peddars coil overs but I have not heard any feedback on them. So what are you guys using for grip in the corners? I need to do something pretty quick.

Also, I am looking for some new full racing tires. What have you guys been using?

Here's what I've read...doing a lot of research myself. No current "cheap" (<$2000) coilover system works better than FE5/Koni + Pedders springs. Eibach springs along with other "lowering" springs coil bind. Current off the shelf, coilover systems for cobalt/ion fail because of both valving and spring rate, including the Pedders coilover and will not perform as well as above-stated setup. Couple people have converted VW Ohlin for rear but that's a whole different ballgame (certainly beyond my level of expertise).

Slotted and specifically drilled rotors are fail for performance due to reduced pad-to-rotor surface area and tendency to crack/warp.

Hard to beat Hoosier A6's for R-comp tires but you gotta pay to play. For street tire, Direzza Star Specs are very popular.

Others will likely chime in with similar feedback. Best of luck to you.

thank you very much. when you said no current cheap coil over, does that mean that there is an expensive one that works well? I am not very worried about budget on this, It just pisses me off to see other cars on rails beat me when I have them doubled in power.
So stock replacements are the way to go with the rotors?

sorry, also do you have numbers for the pedders springs you mention? I want to make sure I get the right ones if there is more than one chioce.

FE5 shocks and struts combined with pedder springs, though you need a special set up made by john powel to make them work with a redline. Uracecars sub frame connectors. upgraded FE5 front sway bar, sphericle bushings for the FE5 arms, rear sway bar by Powel? upgraded knuckles, powergrid endlinks, or any other kind of upgraded endlink.... and I think that is it... I might be missing a few things....

and best bang for the buck as far as strut shock spring combo... http://www.crateenginedepot.com/sto...ck-with-Pedder-Spring-Pkg-TCSS-P2599C515.aspx

also some rotated mounts to help with the wheel hope...

awesome, I have the subframe rails already, and I have the koni yellows, so all I need is the springs themselves.
I have heard that the knuckles are stronger but provide no other advantage???
now I have heard both ways on the front and rear sway bar, some seem to like the upgrade and some say run without them???
Where do you get the spherical bushing from? what kind of performance gains?

Skip the front swaybar. For autox get a Powell Hardcore bar, Powell L CAB's and TCAB's, stock rotors, and some good tires like Yoko Advan AD08's, Dunlap Direzza Star Spec's. If you have never AutoX'd before start small and work your way up. To tell you the truth the more mods that you do the harder the classes that you put yourself in. In those classes the cars are really hard to be competitive with. Just saying.

Forgot one thing. If you don't have a LSD you better put that on the top of your list of things to get for the car.

RiceEater's a pro. Usually if something is missing on the car, he designs and fabricates it himself. He's no n00b. I think he's just wondering about experience related to products currently available. B- you gonna be making your own suspension shit now? heh.

To my knowledge, there is no current high-end coilover setup currently being made for the masses. Saturnracer is one of those who I believe has the VW Ohlin setup...check his facebook page.

If money is no object, you might look into swapping to Cobalt SS/TC front brembos or a Wilwood kit. For most people stock or premium blank rotors and good pads are enough....John Powell has done a shit-ton to his redline in regards to suspension/handling upgrades and is the most highly regarded authority on what works and what doesn't

...the TC knuckle and brembo caliper with a Redline wheel bearing is a direct fit up. the lsj knuckle is not. I use grand am wheel bearings at the front to use a bigger axle. the tooth count is the same for the abs. the abs tooth count for the tc wheel bearing is wrong for a redline and 05 06 cobalts. with correct wheel bearings and brembo brakes changing the hardware the software is ok, the abs is fine doesnt need any changes it works great on the street and on the track with the TC Brembo set up I have track tested it extensively....
What type of competitive driving are you doing, AutoX or track (or both)?

I built and installed an LSD last year, and your right big difference. I am allready in SMF so thay can't ding me any more.
Is John on here anymore? I have some ideas but I wanted to see what was available first.

ok, spent a little time and money today so that brings me to the Pedder springs. are they much stiffer than my eibachs? I guess I could use them with my Koni's up front and just order the balt rear shocks to go with them. Sound good?
If I use them with my Koni up front, what modifications will need to be made if any???

It doesn't seem like many manufacturers are publishing spring rates for "proprietary" reasons but the pedders do not coil bind under load like eibachs and other lowering springs. I do know that there's a guy on GMSC running a cobalt looking to go to 450lb springs in the rear but he's a VERY, VERY good track driver and runs his cobalt as a track car only.

Decent thread here for what is required for the cobalt pedders swap to our cars (front only, rear is direct bolt-on)...

http://www.redlineforums.com/forums/wheels-tires-brakes-suspension/48040-pedder-pedders-redline.html

Actual how to from Qwik (John) on GMSC

Ion to Cobalt spring conversion

I am far from a suspension guru but the biggest issue I have read is getting the car to rotate through corners which requires more overall stiffness --- bonded UCR --- 1.5" rear sway (Powell XXX the best) --- upgraded struts and springs. John also has been working on a new twisting beam for the rear...don't ask me how it works...still learning.

What platforms are major competitors for Street Mod in your region? Chicago is a Turbo 240sx, couple WRX's, and a 3-series Bimmer...uphill battle for me as a novice but I'm determined.

240's, wrx for sure and a bad ass supra are the things to beat.
Where are you in chicago? I still have a house up there. Did you ever come to one of our car club events? we had about 70 cars total between us and the srt4's.

Western burbs (Bloomingdale)...still VERY new to the sport compact scene, just bought my RL back in Dec...always been a "no replacement for displacement" guy but liking my decision to go IRL more every day. (chose it over Focus SVT and SRT4)...Bang for the buck power and handling, it's hard to beat and modifications are relatively inexpensive compared to a lot of other cars.

Went to Pwerks dyno day and CED meet so far this year...met some great people and learning more all the time.

ok, I was on the other side in north west Indiana just over the boarder.

Your links helped out a lot, Now I just have to find the cobalt parts needed.

As for Jonh, how can a guy get ahold of him these days? I never see him on the forum anymore. I use to have his number, but have long lost it.

Hammond?

Glad to help. John sells the swap kit which consists of the cobalt top mount and spacers. As long as your bearings are still good, you can reuse the RL ones. Already have Koni's and I'm picking up Pedders tomorrow a.m. Grabbing some powergrid endlinks next week and then installing everything Aug 6th.

Try sending John PM here or over on GMSC forum or email [email protected].

Assuming you cut the adjustment tab on the Koni's for the front? Bought mine used and they came that way. From what I'm told, mid-range in the front and 3/4 from full soft in the rear should be about the right set-up. Sucks that you can't adjust either while still on the car:(

rice eater. go onto crate engie depot, llok for the sales number and call it. ask for tom and tell him u want the package that john powell and him set uo for the fe5 suspensions conversion. then concact powell and get the spacer u need from him for the strut hats. imho powell is the go to guy for suspension. u ane mail himand ask anything u need to know and he will take the time to help u build a bad ass set up. his car is a track monster... heres his email and u can also go to gmsportcompact.net and pm him there. same screen name as here...

no, but close. I am in chesterton, and grew up in griffith. I set mine to 1/2 in front and that seems pretty good. talking to John he says to switch to the stock tc in the front though.
