I saw a 'GT4 do surprisingly well at Portland on a track filled with 355s. He had gone to stiffer front springs, bigger rear bar, and racing slicks. It also helped that he knew how to drive. |

Yeah, you're going to need more HP, a lot more, to play with a 355 on a big track. Can't you get your friend to a nice small track, or better yet an autocross? |

I have a 77 308 as well...
The suspension is a great place to start your upgrade, but you will also need a good dose of horse power to knock 11 seconds off your times...
Verrell is right though, take a look at your bushings, if they have never been changed they will be looking pretty raunchy after 25 years, I know mine do!
My suspension was do for a complete overhaul last winter, but winter only lasted two days here so I never got around to it, So this winter for sure...
As far as sway bars, the GTS front sway bar is a little bigger than the GTB sway bar, I think the rears are the same size.
Nicks Forza Ferrari, a sponsor here has complete suspension kits for your car, you might give him a call, he's a great guy that supports his products after the sale as well.
My advice to you though, is not to put slicks on your 308 at the track unless everything else is up to snuff, that extra grip can really pull apart 25 year old parts. |

I put on a set of Ohlins shocks and am very happy. The stock konis just don't compare. there is a post, search ohlins. The anti-sway bars you want will depend on the springs one pick. Italian auto has front and rear in 3/4, 7/8, 1". I'm running pretty stiff springs (450f, 400r)and stock GTS (~.70") and it's good in roll, but maybe, but maybe a touch stiff overall. I've never gotten any chatter and it is night and day better than stock. I've heard 350f, 300r with 1"f and 7/8"r is a good street track set up. There is a lot of preference involved though. |

There are shops out there that can make custom sway bars.
You should probably also plan to replace your rubber suspension bushings with polyurethane ones. Too bad you missed last spring's group buy.
There were some previous posts about Koni shocks with adjustable spring perches that you can use to tune ride height, etc.

I am dying to beat my buddy's 355 in my 308 GTB. I am only 11 seconds off his pace at 3.5 mile track. It was suggested to me that to start I would need racing slicks (no probelm) and then need to upgrade the sway bar and suspension before loading up the suspension on the slicks.
Does anyone know of a stronger replacement sway bar that fits the 308 US version.
I will check the posts regarding shocks and springs, but does anyone have any suggestions. I am interested in setting the car up myself. |
